A simple random sample of 49 dog weights is drawn from a population of dog weights that has a mean of 25 pounds and a standard deviation of 2 pounds. The population is not normally distributed, but the sample size is less than 5% of the population size. Show your work. If you use a calculator, you must identify the list(s) and/or function(s), with input(s), you used. Using two decimal places, answer the following: What is the standard deviation of the sample means (show your work)? What is the mean of the sample means (show your work)? What is the probability the sample mean is less than 24 pounds? Give your answer to four decimal places

Investments: The total amount of money in an account with P dollars invested is given by the formula , where r is the rate expressed as a decimal and t is the time (in years). A. If $1000 is invested at 6% interest rate, find the total amount in the account after 6 months. $ (Hint: t is being measured in years in the formula, not months) B. How long will it take an investment of $6000, at an annual rate of 5%, to be worth $615? t= year(s)
