The population of SAT scores forms a normal distribution with a mean of µ=500 and a standard deviation of o =100. If the average SAT score is calculated for a sample of n=25 students,
A. What is the probability that the sample mean will be greater than M=510. In symbols, what is p(M>510)?
B. What is the probability that the sample mean will be greater than M=520. In symbols, what is p(M>520)?
C. What is the probability that the sample mean will be between M=510 and M=520? In symbols, what is p(510<M<520)?
Would the null hypothesis be accepted or rejected in this case?
Dr Johnson wants to know if there is sufficient evidence to conclude that the grade distribution of his class is different than the historical grade distribution.
The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 21.61, Alternative Hypothesis: μ > 21.61. You perform a one sample mean hypothesis test on a random sample of data and observe a p-value of 0.0095. What is the appropriate concl..

Determine the probability that we would reject null hypothesis given that it is true?
For the most recent year available the mean annual cost to attend a private university in the US was $26,889. Assume the distribution of annual costs follows a normal probability distribution and the standard deviation is $4,500. 95% of all studen..
