4-59. In building electronic circuitry, the breakdown volt-age of diodes is an important quality characteristic. The break-down voltage of 12 diodes was recorded as follows: 9.099,9.174, 9.327, 9.377, 8.471, 9.575, 9.514, 8.928, 8.800, 8.920,9.913, and 8.306.(a) Check the normality assumption for the data.(b) Test the claim that the mean breakdown voltage is lessthan 9 volts with a significance level of 0.05.(c) Construct a 95% one-sided upper confidence bound onthe mean breakdown voltage. (d) Use the bound found in part (c) to test the hypothesis.(e) Suppose that the true breakdown voltage is 8.8 volts; it isimportant to detect this with a probability of at least 0.95.Using the sample standard deviation to estimate the popu-lation standard deviation and a significance level of 0.05,determine the necessary sample size.

a)- To check the normality assumption, we can create a histogram and a normal probability plot: Here…

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. R Output: Upon running your analysis in R, you obtain the following results: One Sample t-test data: corn = 0.1121 t = -1.6659, df = alternative hypothesis: true mean is not equal to 130 19, р-value 92 percent confidence interval: 129.3458 130.0342 sample estimates: mean of x 129.69 Questions: (a) State the hypotheses used in performing this test.

according to the department of cars ,trucks , and light duty trucks are driven on an average of about 12,000miles per year,and consume on an average roughly 700 gallons of gas. A. What is the average fuel economy in miles per gallon obtained by these vehicles? B.How meny gallons of gas would the average vehicle save each year if average fuel economy increased by 4 miles per gallon? C Assuming that 21.9 pounds of CO2 are emitted for every gallon of gas consumed, how meny fewer pounds of CO2 would the average vehicle emit annually with a 4 miles per gallon increase in fule economy?
Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of μ = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 40 waves showed an average wave height of x = 16.9 feet. Previous studies of severe storms indicate that σ = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use α = 0.01. (a) What is the level of significance?State the null and alternate hypotheses. H0: μ = 16.4 ft; H1: μ < 16.4 ftH0: μ > 16.4 ft; H1: μ = 16.4 ft H0: μ < 16.4 ft; H1: μ = 16.4 ftH0: μ = 16.4 ft; H1: μ > 16.4 ftH0: μ = 16.4 ft; H1: μ ≠ 16.4 ft…

Based on the constructed grouped frequency table, the median may be expressed as 7B Med = a + 8 where a is the lower class boundary of the median class and ß is the width of the class interval. Find 2a + ß
