The population mean and standard deviation are given below. Find the indicated probability and determine whether a sample mean in the given range below would be considered unusual. If convenient, use technology to find the probability. For a sample of n=33, find the probability of a sample mean being less than 12,749 or greater than 12,752 when u= 12,749 and o = 1.6. For the given sample, the probability of a sample mean being less than 12,749 or greater than 12,752 is (Round to four decimal places needed.)

Cody took his first physics exam and scored an 80. The population mean for this exam is 70, and the standard deviation is 5. What is the probability of selecting a person with a score greater than Cody’s?

You have a uniform distribution whose lowest value is 7 and whose highest value is 15. Find the probability that a randomly selected number from this distribution will be between 9.3 and 10.6.

Please see pictures for details of question.

The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 63, find the probability of a sample mean being less than 19.5 if u = 20 and o=1.33. Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table. For a sample of n = 63, the probability of a sample mean being less than 19.5 if u = 20 and σ = 1.33 is (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it has a probability that is than 5%.

Part C only please. Thank you!
