Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 transactions at random, she found that the average amount spent was $35.25. She then computed a 95% confidence interval to be between $31.84 and $38.66. Which statement gives a valid interpretation of the interval? The store manager is 95% confident that the average amount spent by the 36 sampled customers is between S31.84 and $38.66. There is a 95% chance that the mean amount spent by all customers is between $31.84 and $38.66. O There is a 95% chance that a randomly selected customer will spend between $31.84 and $38.66. The store manager is 95% confident that the average amount spent by all customers is between $31.84 and S3866

A trucking firm has a large inventory of spare parts that have been in storage for a long time. It knowsthat some proportion of these spare parts will have deteriorated to the point where they are no longerusable. In order to estimate this proportion, the firm tests 75 parts, and finds that 0.25 of them are notusable. Find the 95% confidence interval for the population proportion of parts that are not usable. a. 0.25(1 0.25) 0.25(1 0.25) C 0.25 1.96 p 0.25 1.96 0.95 75 75 b. 0.25(1 0.25) 0.25(1 0.25) C 0.25 1.96 p 0.25 1.96 0.95 75 75c. 0.25(1 0.25) 0.25(1 0.25) C 0.25 1.645 p 0.25 1.645 0.95 75 75 d. 0.25(1 0.25) 0.25(1 0.25) C 0.25 1.645 p 0.25 1.645 0.95 75 75

For a scientific Experiment, A physicist must make sure that the temperature of a metal at 0°C gets to no colder than -80°C. the physicist changes the metals temperature at a steady rate of -4°C per hour. Let t represent the temperature in degrees Celsius. Write an inequality. use the fact that the rate of change in temperature times the number of hours equals the final temperature.
