Movie Theater Attendance The data shown are the weekly admissions, in millions, of people attending movie theaters over three different time periods. At α=0.01, is there a difference in the means for the weekly attendance for these time periods? Use the critical value method with tables. 1950 - 1974 1975 - 1990 1991 - 2000 56.7 16.3 22.8 38.3 18.2 26.0 26.0 18.8 28.1 18.9 20.5 26.8 19.9 23.9 25.2 16.5 25.6 27.7 Assume that all variables are normally distributed, that the samples are independent, that the population variances are equal, and that the samples are simple random samples, one from each of the populations

Consider the bivariate data shown in the table. X y Compute (x)². 8 10.2 9 9.9 10 8.6 11 7.7 12 13 6.8 5.9 14 15 4.2 3 16 2.1

A. What is the percentile rank for X=38? B. What is the percentile rank for X=38?

Over doses from opioids have captured the national spotlight. Rightly so they kill nearly 30,000 Americas a year and cause more than 1 million hospitalizations. However, the misuse of over-the-counter pain medications (e.g. Tylenol, Advil, Aleve) can cause stomach bleeding, ulcers, liver disease and, in some cases, death. Approximately 80% of Americans use these medications to relieve headaches, backaches, sore muscles, and reduce fever but they are unaware of the dangers if the drugs are not used correctly. A random sample (n=101) of adults were given a questionnaire to ask the question "How often do you use pain medication in one day?". Using the output, histogram, box- whisker plot, and the QQ Plot attached - check the assumption of normality for this data. PainNormalityInformationoutputhistbox 210317.pdf The assumption of normality was checked by comparing the and the median. This suggests that the distribution is slightly The + The is between the acceptable range of -3 and +3.…
