3.) What is the critical value for a left-tailed z-test for the mean with 95% confidence? 4.) If the critical values in a two-tailed test are -1.23 and 1.23, would you reject the null hypothesis for a test value of 1.62? 5.) The mean IQ for humans is defined to be 100. A particularly cynical researcher believes that the actual mean IQ is significantly lower than this. The researcher tests the IQs of a sample of 101 people, and finds that the mean of the sample is 98, with a sample standard deviation of 4. Find a test value for a t-test for the mean based on this study.
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.

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. She randomly sampled 15 books from the library, test her claim at a 0.05 level of significance. number of times checked out number of pages 13 223 45 350 49 377 30 371 3 343 7 280 17 218 7 265 20 382 23 287 1 313 30 388 20 358 2 311 40 421 The correlation coefficient: r= (round to 3 decimal places) The equation y=a+bx is: (round to 3 decimal places) y=+ x The hypotheses are: H0:ρ=0H0:ρ=0 (no linear relationship)HA:ρ≠0HA:ρ≠0 (linear relationship) (claim) Since αα is 0.05 the critical value is -2.16 and 2.16 The test value is: (round to 3 decimal places) The p-value is: (round to 3 decimal places) The decision is to reject H0H0 do not reject…
