There are two parts to this problem: A). Yesterday's low temperature of 13 cities was recorded with the following scores: 15, 16, 20, 22, 31, 37, 46, 47, 48, 49, 57, 58, 64 Find the median, first quartile, third quartile, and the IQR. Are there any outliners according to the 1.5* IQR rule? B.) Suppose in problem A the city reported that 15 degrees made a mistake - it should have been 5 degrees instead of 15 degrees. How will each of the following measures be affected (increase, decrease, or no change) by replacing 15 with 5? Provide the Median, Mean, IQR, Range, and Standard Deviation.
In 2015, the average duration of long-distance telephone calls from a certain town was 3.9 minutes.A telephone company wants to perform a test to determine whether this average duration of longdistance calls has changed. Fifty calls, originating from the town, was randomly selected and thefollowing summary minutes.∑ ? = 205 ∑(? − ?̅)∑(? − ?̅)2 = 56.43 a) Calculate the sample mean, ?̅. b) Calculate the sample standard deviation c) Using the p value approach at the 1% level of significance, test whether the mean duration oflong-distance calls from the town had increased. d) Construct the 99% confidence interval for the population mean duration of the long-distance calls from the town.

Steel rods manufactured in a plant must be a minimum of 2 metres in length in order to pass through an inspection procedure. Steel rods with lengths that are normally distributed, with a mean of 2.1 metres and a standard deviation of 0.1 metres, are produced during the manufacturing process. A random sample of 25 steel rods is chosen, and their lengths are measured using a tape measure. i. Decide on the appropriate distribution of the sample mean of the 25 steel rods in the sample using the appropriate distribution formula. ii. Calculate the probability that the sample mean of steel rods that meet the minimum length requirement is the same as the mean of the entire sample. iii. For example, if the observed sample mean length of steel rods is 2.15, calculate the 98% two-sided confidence interval for the true mean length of the manufacturing process, assuming that it is not known.

A student wants to see if the number of times a book has been checked out of the library in the past year and the number of pages in the book are related. She guesses that the number of times a book has been checked out of the library in the past year will be a predictor of the number of pages it has.

The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a 10% level of significance. Give answer to at least 4 decimal places. Hours 49 40 58 52 49 70 49 59 47 49 53 55 What are the correct hypotheses?

The correct summary would be: that the mean number of hours of all employees at start-up companies work more than the US mean of 47 hours.
In 2015, the average duration of long-distance telephone calls from a certain town was 3.9 minutes. A telephone company wants to perform a test to determine whether this average duration of long- distance calls has changed. Fifty calls, originating from the town, was randomly selected and the following summary minutes. ∑ ? = 205 ∑(? − ?̅)2 = 56.43 a). Using the p value approach at the 1% level of significance, test whether the mean duration of long-distance calls from the town had increased. b). Construct the 99% confidence interval for the population mean duration of the long-distance calls from the town.
