What is the p-value for the following hypothesis test. H0 M equals 23 H1 M not 23 n equals 50 x-bar equals 21.25 standard deviation equals 5?
okay wikianswers messed up the question. H0: M=23; H1: M not 23; n=50; x-bar = 21.25; standard deviation = 5. please help!
What is the mean and standard deviation of 60 percent of 300?
There is insufficient information in the question to answer it. In order to compute a mean and a standard deviation, you need at least two data points, but the question only gave one. Please restate the question.
What is the z-score for 45.00?
There is insufficient information in the question to properly answer it. In order to compute a Z score from a raw score, you need the mean and the the standard deviation, neither of which was given. Please restate the question.
What percentage of people have IQ's at 118?
How can I find out what is considered a 'good' IQ? I got a score of 118 and am wondering if that is normal or slightly above? Can anyone answer? Please email me directly: abigail.f.miller@gmail.com.Thank you in advance and I appreciate the help.Sincerely,AbigailIQ is a statistic based on standard deviation, that is how far the subject is from the baseline (or average). Each standard deviation is granted 12 or 16 points depending on the test. A single standard deviation is 68.2% of the popuation, meaning 68.2% of people have within 12-16 IQ points of 100. 100 being the baseline average.Assuming half fall above average and half fall below, this means that only 15.9% of the population has above a 112 or 116 IQ depending on the actual test scaling. So, in either case you are in the top 15.9% in regards to raw IQ.
Is the standard normal curve is between Z -3.00 and Z 3.00?
Your question is confusing. However, I will answer the following question, and if this is not your question, please re-submit What is the area under the standard normal curve for z = -3 to Z = 3? The standard normal has a mean of zero and standard deviation of 1. The answer is: 0.9973 This is the equivalent of saying the probability of Z in the range of -3 to +3 is 0.9973 and above 3 it is 0.0027/2 or 0.00135 and below -3 it is 0.00135. Values of the normal distribution can be found in the Internet and textbooks on statistics.
Can standard deviation be a negative?
No. Standard deviation is the square root of a non-negative number (the variance) and as such has to be at least zero. Please see the related links for a definition of standard deviation and some examples.
Is it true that the standard deviation is equal to the square root of the variance?
Yes. Please see the related link, below.
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.

What z-score corresponds to this value?
There is insufficient information in the question to answer it. To determine Z score, you need raw score, mean, and standard deviation. Please restate the question.
What is the z score for 0.71?
This question cannot be answered. You need the mean and standard deviation in order to compute a Z score for a Raw score. Please restate the question.
What is the z-score for a test score of 110?
In order to know the z-score, given a test score, you must also know the mean and the standard deviation. Please restate the question.
What is the z-score for 45.00?
There is insufficient information in the question to properly answer it. In order to compute a Z score from a raw score, you need the mean and the the standard deviation, neither of which was given. Please restate the question.
How many teaspoon equals 1 c?
A "c" is not a standard measure that we know. -please re-write when you know the measure.
What is the z score of 6.56 and how do you find it?
There is insufficient information in the question to answer it. To determine Z-Score, you need raw score, which you gave, but you also need mean and standard deviation, which you did not give. Please restate the question.
