- We use the dataset "MASchools" in the package "AER". The dataset contains information on test performance, school characteristics and student demographic backgrounds for school districts in Massachusetts (MA). In this exercise, we shall use R-functions in the packages "estimatr", "car" and "ggplot2". Whenever you need to compute standard errors, the type of standard error should be "HC1"or equivalently "stata". The R-code below is supposed to generate a graph similar to Figure 9.1 of Stock and Watson (the left graph on page 19 of Lecture Slides 7) with the three estimated regression functions. However, when you implement it, you find that the resulting graph has a problem. Choose the wrong statement about the code and/or the generated diagram. a. The resulting graph shows the data points. b. The error can be fixed by changing the location of one of the '+' symbols in the code. c. The unknown expression y ~ poly(x,3) causes the error. d. The x and y in the formula of geom_smooth are…The average time period that spouses survive after the death of their partner is said to be greater for widows than for widowers. A sociologist who wishes to evaluate such claim obtained survival data (in years) following the death of a spouse on randomly selected 10 widows and 8 widowers. Software Output: Shapiro-Wilk TestFor Widows: data: survival p-value = 0.57For Widowers: data: survival p-value = 0.98Levene’s Test for Homogeneity of Variance p-value = 0.98 What is the most appropriate test procedure to test the claim? a. Z-test b. Pooled t-test c. Non-pooled t-test d. Mann-Whitney TestSOLVE FOR CRITICAL VALUE Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measures in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in x1 = 290 and s1 = 12 while another random sample of 16 gears from the second supplier results in x2 = 321 and s2 = 22. Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength. Use a =0.04, and assume that both populations are normally distributed with equal variances.Level of significance = 0.04

Your supervisor asked you to compare the two different prototypes by the teams. You need to examine 50 AirTag samples from each team (i.e., total of 100 AirTags from both teams) and measure their maximum Bluetooth range. Use the maximum Bluetooth range results for the prototypes designed by team A and team B shown in table 1 below to determine the following: (1-a) What is the mean, mode, median, and standard deviation of the maximum Bluetooth range for each team of AirTag? Show all work. (1-b) Divide each data group into five categories and create the frequency table. (1-c) Calculate the mean and standard deviation from the frequency tables and compare them to the results found in part (1-a). (1-d) Present the data as a histogram.
