Standardized measures seem to indicate that the average level of anxiety has increased gradually over the past 50 years (Twenge, 2000). In the 1950s, the average score on the Child Manifest Anxiety Scale was μ = 14.1. A sample of n = 15 of today’s children produces a mean score of M = 23.3 with SS = 240. Based on the sample, has there been a significant change in the average level of anxiety since the1950s? Use a two-tailed test with α = 0.01.

You run a publishing company and you are assessing your proofreaders. You hope that they can proofread an average of 1000 words per hour, an industry benchmark, If they average fewer than 1000 words per hour you will need to reconfigure the staffing. You test the proofreading times of a sample of 100 of the proofreaders and find the sample average words per hour is = whether the population mean words per hour is greater than 1000 with a 95% confidence level. The z-critical value for this test is Z = Zo.05 975 and the sample standard deviation is s = 600. Test 1.645. Show all your steps clearly and illustrate your answer with a graph. %3D
Q2. You collected 500 weeks of data (2500 days total). Based on that you find Tuesday's mean return is 12 bps. Mean return of all days is 2 bps. Stdev across all days is 100 bps. There is no noticeable difference b/w Tuesday stdev vs other weekdays' stdev.Q2d. Based on 95% CI, should you reject or accept that Tuesday's mean return is not different from other weekdays?
