Please show all diagrams and work. Circle your answers. 1. The average weight of an NFL player is 245.7 pounds with a standard deviation of 34.5 pounds, but the probability distribution of the population is unknown. If a random sample of 32 NFL players is selected, what is the probability that the average weight of the sample will be less than 234 pounds.

A statistics professor asks each of the students in an introductory statistics lecture to fill out a survey. There are 100 students in the course, and each one filled out the survey. One of the questions asked students to state their age. The data are included below. Use Excel to calculate the population standard deviation and the population variance. Round your answers to one decimal place. Do not round until you've calculated your final answer "Age of students"19201918201917172324212121221920221818181919202017212118202119182020212021202137192219212219194324232022172119201820222221192022191818182217191923211718202020202418223020192222192318201921211920202018

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 3331 grams and a variance of 362,404. If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be less than 3812 grams. Round your answer to four decimal places. alt gle.
