Use the normal probability applet to find the combined area under the standard normal curve that is to the right of z = 1.358 and to the left of z = -1.358. (Round your answer to3 decimal places. Example: If the answer is 0.8976 then you would enter 0.898 in the answer box.) Use the following information to answer the next 5 questions.Suppose the mean GPA of BYU-Idaho students is 3.5 and the standard deviation is 0.7. It is well known that this distribution is left-skewed. A random sample of n = 81 students will be drawn.Question 21 / 1 ptsWhat is the mean of the distribution of the sample means (sampling distribution) for all possible samples of size 81 that could be drawn from the parent population of GPAs? (Round your answer to 1 decimal place. Example: If the answer is 1.2873, then you would enter 1.3 in the answer box.) Question 31 / 1 ptsWhat is the standard deviation of the distribution of the sample means (sampling distribution) for all possible samples of size 81 that could be drawn from the parent population? (Round your answer to 3 decimal places. Example: If the answer is 0.8976 then you would enter 0.898 in the answer box.)
