The following data are the Medical Expenses in each of the 50 states. Using descriptive statistics, measures of central tendency, and measures of dispersion, answer the following questions below.The data is in thousands of dollars and is arranged in alphabetical order Q 1: Using the formula: (2 ^^ k> n.)Determine the result of that mathematical operation, to determine the number of classes. Q 2: Based on the previous result. Determine the number of classes. Q 3: Using the formula: class width = H - L / (number of classes). Determine the result of that mathematical operation to two decimal places to determine the width of the classes.Write the result as follows (XXX .XX) Q 4: Based on the previous result, determine the width of each "Cute Width" class if the initial value of the first class is 400 and the final value of the last class is 1300.

We want to know if the average rating of attractiveness (1=homely, 5=stunning) of a typical person differs depending on the state they are located in. We believe that there will be significant differences in the average attractiveness of the people at each of the four states we examine. 1) Report (in words or statistical notation), our null and alternative hypothesis: Provided are the data we collected from four different states: OR, WA, ID, and CA (see below): OR WA ID CA X bar 3.01 3.07 2.88 3.7 SD 0.42 0.60 0.46 0.30 n 10 10 10 9 SS 92.19 97.47 84.84 123.95 2) Given that we have more than two samples, we need to conduct a one-way ANOVA. Conduct the test in order to calculate the F-statistic addressing our hypothesis. Be sure to calculate the grand mean and the between-groups & within-groups mean-squares first (also don’t forget to round to 2 decimal places and report the formulas!!): 3.) Calculate the degrees…
According to the Pew report, 14.6% of newly married couples in 2008 reported that their spouse was of another race or ethnicity (CNNLiving, June 7, 2010). In a similar survey in 1980, only 6.8% of newlywed couples reported marrying outside their race or ethnicity. Suppose both of these surveys were conducted on 500 newly married couples. (You may find it useful to reference the appropriate table: z table or t table) Let p1 represent the population proportion in 2008 and p2 the population proportion in 1980. a. Specify the competing hypotheses to test the claim that there is an increase in the proportion of people who marry outside their race or ethnicity. multiple choice 1 H0: p1 − p2 = 0; HA: p1 − p2 ≠ 0 H0: p1 − p2 ≤ 0; HA: p1 − p2 > 0 Correct H0: p1 − p2 ≥ 0; HA: p1 − p2 < 0 b-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.) b-2. Find the p-value.…

10. A study is conducted to determine if the blue light from a tablet device will affect the fall asleep time of people in various age groups differently. Volunteers for the study are grouped by age: 18-30, 31-50, and 50+. Half of each group is assigned a standard tablet, the other half is assigned a tablet with reduced blue light. People in each group are asked to use the tablet for 10 minutes before bed and their fall asleep time is recorded. Which of the following is correct? (A) Blocks: the three age groups. Treatments: using the standard tablet or the reduced blue light tablet before bed. Response variable: How the eyes react to blue light. (B) Blocks: the three age groups. Treatments: measuring how long it takes to fall asleep. Response variable: The hours of sleep recorded. (C) Strata: the three age groups. Treatments: using the standard tablet or the reduced blue light tablet before bed. Response variable: How the eyes react to blue light. (D) Blocks: the three age groups.…
Workers at an aluminium plant are placed into categories based on their duration of exposure, (in years) to aluminium disease and level of disease prevalence. Category 1- heavily diseased, category 2- lightly diseased and category 3 – normal. There is a need to determine if there is a relationship between the duration of exposure and the categories. Duration of Exposure <1 1 to 5 >5 Heavily diseased 10 8 23 Lightly diseased 9 19 11 Normal 70 136 206 Do the following: explain the hypothesis test you would use in this analysis. determine whether you can conclude that the proportions of workers in the various disease categories differ among exposure levels. You need to first set up an alternate and null hypothesis and give all details of the level of confidence testing is being done at.
