An agronomist wanted to estimate the mean weight of a certain fruit (?) in his farm. He selected a random sample of size ?=16, and found that the sample mean ?̅=55 gm and a sample stranded deviation ?= 3 gm. It is assumed that the population is normal with unknown standard deviation (?).

a) Find a point estimate for (?).

b) Find a 95% confidence interval for the population mean (?).

12. A bank wanted to use a sample of account balances to estimate the mean savings of its customers. a) A small pilot study found the savings to be approximately normally distributed with a mean of $1410 and a standard deviation of $242. A 99% confidence interval is to be used and a maximum error of $42 is desired. How many customers should be sampled? [3] b) In the sample, 114 people had savings greater than $1000. Using the sample...

An engineer wanted to estimate the true mean resistance of a certain electrical circuits (?) by a sample mean (?̅). It is known that the population is normal, and the population standard deviation is ?=0.25 ohms. Determine the required sample size (?) so that he will be 90% confident of being correct within ± 0.06.

A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 55 specimens and counts the number of seeds in each. Use her sample results (mean = 15.1, standard deviation = 20.7) to find the 80% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. Give a step by step breakdown. 80% C.I. = __(11.523,18.677)________________
