With Question 1- I am having issues with the two questions. I get the mean U= 7.5, the Standard Deviation is 1.3 and I am stuck with the 75th percentile. Can you please assist

Question 1: Potatoes:Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of7.5ounces and a standard deviation of1.3ounces.

(a) Carl only wants to sell the best potatoes to his friends and neighbors at the farmer's market. According to weight, this means he wants to sell only those potatoes that are among the heaviest25%. What is the minimum weight required to be brought to the farmer's market?Round your answer to 2 decimal places.

With Question 2 I get the mean is 8.1, Standard deviation is 1.3 and the sample N is 6 but I get stuck with the putting the equation together.

Question 2 Potatoes - Samples:Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of8.1ounces and a standard deviation of1.3ounces.

Suppose Carl bags his potatoes in randomly selected groups of6. What percentage of these bags should have a mean potato weight between7.5and8.5ounces?Enter your answer as a percentage rounded to one decimal place.
