Please answer step by step, applying estimate formulas, use of
tables, as well as any assumptions needed to solve the problems.
The previous answer you provided me was incomplete. I need
calculations and formulas.
A research company conducted a
survey to determine the average amount smokers spend on cigarettes
in a week. The company found that the distribution of amounts they
spend per week tended to follow a normal distribution, with a
standard deviation of $5. A sample of 49 smokers revealed that the
average weekly spending was $40. What is the point estimator of the
population mean? Explain your answer. Using the 95% confidence
level, find the confidence interval for the population mean.
Explain its meaning.
