What is the probability of asking a student at your school what grade he or she is in?
The probability is indeterminate. I might ask a student or I might not.
What is the minimum grade a student must get in order to receive an A's if the mean grade was 72 and the standard deviation was 9?
Different examinations have different thresholds for A grades.
What is the probability in decimals of a student getting at least one answer correct out of ten true or false questions?
0.05 I think is the answer
What are 5 questions you could ask a student about probability distribution?
The answer depends on the level at which the student is expected to be. A 15-year old should know the probability of getting heads on the toss of a coin but even a mathematics graduate - who did not specialise in probability - would be expected to be able to prove the mathematical relationship between the Normal distribution and the F-distribution. If asked, most student would not even know what the second part of the sentence meant.

When the population standard deviation is not known?
Context of this question is not clear because it is NOT a full question. However when attempting to estimate an parameter such as µ using sample data when the population standard deviation σ is unknown, we have to estimate the standard deviation of the population using a stastitic called s where _ Σ(x-x)² s = ▬▬▬▬ n -1 _ and estimator for µ , in particular x ........................................._ has a standard deviation of s(x)= s/√n and the statistic _ x - hypothesized µ T = ▬▬▬▬▬▬▬▬▬▬ s has a student's T distribution with n-1 degrees of freedom If n> 30 , then by the Central Limit Theorem, the T distribution approaches the shape and form of the normal(gaussian) probability distribution and the Z table may be used to find needed critical statistical values for hypothesis tests , p-values, and interval estimates.
5000 students participated in a certain test yielding a result that follows the normal distribution with means of 65 points and standard deviation of 10 points.?
5000 students participated in a certain test yielding a result that follows the normal distribution with means of 65 points and standard deviation of 10 points.(1) Find the probability of a certain student marking more than 75 points and less than 85 points inclusive.(2) A student needs more than what point to be positioned within top 5% of the participants in this test?(3) A student with more than what point can be positioned within top 100 students?i dont understand the question.. could you help me??pls....

What is percent deviation?
Percent deviation formula is very useful in determining how accurate the data collected by research really is. Percent Deviation = (student data-lab data) / lab data then multiplied by 100 Note: If the percent deviation is a negative number that means the student data is lower than the lab value.
A class can read an average of 175 wpm with a standard deviation of 20wpm. The top 3percent in the class get an award.What is the minimum number of wpm a student would have to read to get an award?
