A primer paint can be used on aluminum panels. The primer's drying time is an importantconsideration in the manufacturing process. Twenty panels are selected, and the drying timesin hours are as follows:1.6, 1.3, 1.5, 1.6, 1.7,1.9, 1.8, 1.6, 1.4, 1.8, 1.9, 1.8, 1.7, 1.5, 1.6, 1.4, 1.3, 1.6, 1.5, 1.8.Use the Wilcoxon signed-rank test. Is there evidence that the mean drying time of the primerexceeds 1.5 hours? Use a = 0.05. Match the answers.a.

A state fisheries commission wants to estimate the number of bass caught in a givenlake during a season in order to restock the lake with the appropriate number ofyoung fish. The commission has information on the seasonal catch (CATCH) inthousands of bass per square mile; the size of the lake in square miles (SIZE); thenumber of lakeshore residences per square mile (RESIDENCE); the number of livingplaces for bass (i.e. weed beds, sunken trees, drop offs etc.) (STRUCTURE) andACCESS a dummy variable equal to 1 if the lake has public access and 0 if not. What do you think are the expected signs of the regression coefficients?Justify your choice. Using R-studio, estimate the multiple linear regression model.

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision.

The eleven regular employees of Migdol Corporation were asked to proceed to the clinic for their annual physical examination. As part of the process, their temperatures were taken by the company nurse, which were then recorded on their APE Forms. The temperatures of the eleven employees were as follows: 37.18oC, 36.09oC, 36.81oC, 37.42oC, 35.93oC, 37.65oC, 36.44oC, 37.28oC, 37.52oC, 36.31oC, and 37.79oC. However, the company nurse had made a mistake in recording the first and ninth temperatures. The temperature of the first employee was 0.09oC higher, while the temperature of the ninth employee was 0.11oC lower. Assume that the values were normally distributed. (a.) If six samples were selected, specifically – the first, fourth, fifth, eighth, ninth, and tenth, what was the standard deviation of the sample using the correct values? (b.) If six samples were selected, specifically – the first, fourth, fifth, eighth, ninth, and tenth, what was the variance for the eleven officers? (c.) If…
