Z-Distribution Intervals 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. Write a brief explanation of the meaning of the confidence interval in the context of this problem For a party with 35 clients, use part (b) to estimate a range of dollar values for Collette's total sales at that party.
Background of the Case: You are given the dataset representing the monthly salaries from a sample of thirty (30) Data Scientists. You wish to find the actual average salary that a data scientist would earn. However it would be impractical to gather all the data scientist in the world to get their salary information. Hence, you settle with analyzing the sample. The population standard deviation is known to be P 15,000. Find the Confidence Interval with a confidence level of 90% the data is in the picture

Constructing a Confidence Interval for a Population Mean A biologist measures the lengths of a random sample 30 mature brown trout in a large lake and finds that the sample a mean weight of 41 pounds.

He tests 20 children selected at random and finds that their mean attention span is 32 minutes with a standard deviation of 5 minutes. If we assume that attention spans are normally distributed, find a 95% confidence interval for the mean attention span of children playing with this new toy. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
