Hello, I want to check my work. I used invNorm on a calculator. If there an excel formula I can use? Can you please explain these steps to solving this problem? Thank you! You want to obtain a sample to estimate a population mean age of the incoming fall term transfer students. Based on previous evidence, you believe the population standard deviation is approximately 6.5. You would like to be 90% confident that your estimate is within 2 of the true population mean. How large of a sample size is required? n = Use technology to find z-score. Give your answer in whole people. Make sure you use the correct rounding rule for samples size.

What type of problem is this what is the formula to solve it? The average American consumer in 2018 spent $7,923 on food and drink. Assume the amount spent is normally distributed and that the standard deviation is $1,592. What percentage of Americans in 2018 spent more than $9,000 on food and drink? Enter your answer as a number rounded to three decimal places, e.g. 0.951
For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.How hard is it to reach a businessperson by phone? Let p be the proportion of calls to businesspeople for which the caller reaches the person being called on the first try. (a) If you have no preliminary estimate for p, how many business phone calls should you include in a random sample to be 80% sure that the point estimate p̂ will be within a distance of 0.06 from p? (Round your answer up to the nearest whole number.)phone calls(b) A report states that businesspeople can be reached by a single phone call approximately 18% of the time. Using this (national) estimate for p, answer part (a). (Round your answer up to the nearest whole number.)phone calls
Hi, I've been confused about the problem since I can't seem to find the population mean. I've attached a picture of the problem. Thanks !!
The biologist wants to estimate the average age of Coyotes in Tuolumne County. Her estimates from past experience suggest the standard deviation is 1.3 years. How big of a sample should she take to be 95% sure his estimate is off by no more than 3minutes?
