The GPAs of all students enrolled at a large university has an approximately normal distribution with a mean of 3.02 and a standard deviation of 0.29. Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.07 or higher. Round your answer to four decimal places.

Step 1
Given that the standard deviation of the population is 0.29 and the sample size is 20, we can calculate the standard deviation of the sampling distribution using the formula: standard deviation of sampling distribution = population standard deviation / sqrt(sample Show more…

The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of 0.29. Find the probability that the mean GPA of a random sample of 20 students selected from this university is 2.90 or lower. Round your answer to four decimal places.

The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and standard deviation of 0.29. Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.09 or higher. Round your answer to four decimal places.

Undergraduate GPAs It is desired to estimate the mean GPA of each undergraduate class at a large uni- versity. How large a sample is necessary to estimate the GPA within 0.25 at the $99 \%$ confidence level? The population standard deviation is $1.2 .$
