Collette is self-employed and sells cookware at home parties. She wants to estimate the average amount a client spends at each party. A random sample of 35 receipts gave a sample mean of $34.70 with sample standard deviation $4.85. Find a 95% confidence interval for the average amount spent by all clients.

Collette is self-employed, selling stamps at home parties. She wants to estimate the average amount a client spends at each party. A random sample of 35 clients' receipts gave a mean of x̄ = $34.70 with standard deviation ̃̃ = 4.85. a. (8pts) Find a 90% confidence interval for the average amount spent by all clients b. (5pts) For a party with 35 clients, use part (a) to estimate a range of dollar values for Collette's total sales at that party.

Collette is self-employed, selling items at Home Interior parties. She wants to estimate the average amount a client spends at each party. A random sample of 35 clients' receipts gave a sample mean of $34.70 and historically we know the population standard deviation of spending at these parties to be $4.85. Explain why you may assume your data is normally distributed. Find a 90% confidence interval for the average amount any given client can be expected to spend at a party

Collette is self-employed, selling cosmetics at home parties. She wants to estimate the average amount a client spends per year at these parties. A random sample of 16 receipts had a mean of x̄ = $340.70 with a standard deviation of s = $60.15. Find a 90% confidence interval for the mean amount μ spent by all clients. Assume x has a distribution that is approximately normal. a. What is the critical value of the t variable for the given confidence level? b. What is the maximal margin of error? c. The lower endpoint of the 90% confidence interval for μ is d. The upper endpoint of the 90% confidence interval μ is round your answers to the nearest hundredth
