Distribution would be centered at .14*128=17.92
The standard deviation of the distribution would be root(n(p(p-1)))=root(128*.14*.86)=3.92571013
Normal, unimodal

Explain why binomial nomenclature is used to name plants?
Binomials consists of the Genus name and the specific epithet. thus, by just looking at it we see informations about the plant species. First, we will know that it belongs to that particular genus and therefore has the diagnostic characteristics of that particular genus. the specific epithet is an "adjective" that describes the species (usually). For example,longifolia means the species has large leaves or albusmeaning white.
The Difference Between a Qualitative and Quantitative Pregnancy Test?
A pregnancy test can be performed early in pregnancy to predict conception or gestational age. Urine-based pregnancy tests detect pregnancy hormones in urine for a positive or negative result. Blood tests measure how much of a pregnancy hormone is present.Qualitative Pregnancy Test – UrineHome pregnancy test kits and urine pregnancy tests given by a physician are qualitative. Qualitative refers to the method of diagnosing pregnancy. Urine tests measure the presence of human chorionic gonadotropin (hCG) in urine. If hCG is present, the test results are positive. If no hCG is found in urine, the test will be negative.False negatives are more common with a urine pregnancy test than false positives. False negatives can be caused by frequent urination due to high fluid intake and miscalculated start day of current menstrual cycle. False positives are typically linked to fertility treatments and prescription medications that include hCG as a means of increasing chance of conception.Quantitative Pregnancy Test – BloodA blood pregnancy test can be ordered as early as five to 10 days after unprotected intercourse. Blood pregnancy tests measure hCG levels in quantity rather than just a true or false result. Quantities can then be compared to normal levels as a means of gestational age prediction. In some cases, quantitative pregnant test results are higher than normal. Normal hCG levels at five weeks gestation fall between 18 and 7,340 mlU / ml. Measurements at the higher end of the range could mean medical issues with the pregnancy or multiple fetuses. Blood hCG levels will continue to rise until peaking between nine and 12 weeks gestation. After the 12th week, levels gradually fall until birth.Medical Treatment and Pregnancy TestDue to the possibility of false negative pregnancy test results, women who believe they may be pregnant should exercise caution when taking prescription and over the counter medications deemed unsafe during pregnancy. Diagnostic testing, such as X-rays and radiation-based testing should only be performed when medically necessary. Precautions include lead aprons placed over the abdominal area during X-rays. Prescription medications fall into pregnancy categories based on clinical testing and results. Categories include A, B, C, D and X.Category A drugs have been thoroughly tested for use during pregnancy and deemed safe. Category B is designated after animal testing revealed no signs of fetal harm. Category C may be linked to fetal damage in animal testing. Category D includes drugs proven to cause harm to a human fetus, but benefits from medications in this category could outweigh risks. Category X is reserved for medications that should never be used during pregnancy.
Normal PSA Levels?
In men over 40 years of age, is common for doctors performing blood tests on their patients to examine Prostatic Specific Antigen (PSA) levels. PSA is a protein produced by the male prostate gland. If the PSA level is above certain levels, or has shown to be getting progressively higher over a number of tests conducted over a period of time, it serves as a warning sign of either prostate cancer or other noncancerous prostatic diseases. A normal PSA level does not completely rule out the possibility of prostate cancer. Many doctors are of the opinion that any male who lives long enough will eventually develop prostate cancer, but that it may not necessarily be the cause of death. Given the somewhat vague nature of the results supplied by PSA testing, it is also necessary to consider adding a colonoscopy to the equation along with occasional digital prostate exams. The PSA test, however, is a popular diagnostic tool, since it is noninvasive in nature. Knowing normal PSA levels will assist a personal care physician in determining a patient's prostate cancer risk when other factors, such as family history are included. A PSA level of below four ng/ml (nanogram/milliliter) is often used as the basis to eliminate concern about the risk of prostate cancer, even though this level does not completely eliminate the possibility. A PSA level below four combined with a digital examination that indicates normal prostate size means that there is only a 15% chance of prostate cancer being present. This increases to 25% for PSA levels between four and 10. Anything above 10 represents an increase to 67%. Some experts in the area of PSA levels promote using lower numbers, less than 2.5 or 3.0 ng/ml to represent normal values. This is particularly applicable to younger patients who have not experienced the normal prostate gland the enlargement that accompanies advancing age. Equally important to the PSA number is the trend of that number. Is it going up, how quickly, over what period of time? These are questions doctors will consider on a patient by patient basis?
