The police chief selects a sample of 49 local police officers from a population of officers with a mean physical fitness rating of 72 ± 7.0 (µ ± 0) on a 100-point physical endurance rating scale. He measures a sample mean physical fitness rating on this scale equal to 74. He conducts a one-independent sample z test to determine whether physical endurance increased at a .05 level of significance.

The color of the Star Trek uniform represents each crew-member's work area. In the original Star Trek series, blue shirts are worn by medical and science staff, gold shirts are worn by the command division, and the red shirts were worn by engineering, security and communications division. We will statistically assess whether there is a connection between uniform color and the fatality rate. The table below shows a sample of how many crew-members in each area have died onscreen and their shirt color. Use a = 0.05 to test to see if a crew-member's fatality onscreen is dependent on their uniform color. Alive Dead Blue 39 Gold 21 Red 28 Total 88 8 9 27 44 Total 47 30 55 132
The first test a doctor would order to determine whether a person is infected with HIV (the virus that causes AIDS) is the ELISA test. It detects antibodies and antigens for HIV. A study in Statistical Science by J. Gastwirth estimated that, if the person is actually infected with HIV, this test produces a positive result 97.7% of the time. If a person is not infected with HIV, the test result is negative 92.6% of the time. According the the US Centers for Disease Control (CDC), an estimated 1.1 million Americans out of a population of 321 million were infected with HIV in 2015. Using the information above, determine the probability that a randomly selected person whose ELISA test is positive actually is infected with HIV? a. What is the probability that a randomly selected American is infected with HIV? b. Using the answer to part (a) and the conditional probabilities of positive and negative ELISA test results, fill out the contingency table below: ELISA Test Result…

Assignment #6 For this assignment, you will be using the Tips Dataset file in Excel. The file contains both qualitative and quantitative variables. Choose two qualitative variables. You will be using a hypothesis test to determine if the two variables are associated. 1. Which two variables did you choose? Create a table to summarize the data from the data file. Example below: Example: Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data). Response Male Female Total Not at all 23 25 48 Somewhat 13 22 35 Very Total 26 16 42 62 63 125 2. Which hypothesis test is appropriate for this type of data? Explain. What is your null hypothesis? What is your alternative hypothesis? 3. Conduct the hypothesis test. Include any output from Excel. What is your test statistic? Using alpha = 0.05 determine the results of your hypothesis test. Explain. 4. Interpret your results into a conclusion based on…
