- The Weight and Blood Pressure of 26 Randomly Selected Male People in a Group ages 25 to 30 are shown in the following table. Suppose weight and blood pressure are normally and jointly distributed Y= 69.1044 + 0.4194x A)Test the hypothesis that rho = 0 and test the hypothesis that rho = 0.6Suppose that the lifetime in years, X, of a type of electrical switch follows the distribution f(x)=12e−x2f(x)=12e−x2for x>0x>0. What type of continuous distribution is this and what is the average lifetime of one of these switches?Suppose that X has a discrete uniform distribution on the integers 0 through 9. Determine the mean, variance, and standard deviation of the random variable Y = 5X and compare to the corresponding results for X.
- From the analysis of wages paid to employees in two service organizations X and Y, the following were obtained: Organization X Organization YNumber of wage earners 550 650Average monthly earnings 5,000 4,500Variance of the distribution of wages 900 1600 (i) Which organization pays a larger amount as monthly wages? (ii) In which organization is there greater variability in individual wages of all the wage earners taken together?A company pays its employees an average wage of $22.50 an hour with a standarddeviation of $2.30. If the wages are approximately normally distributed and paid to thenearest centavos, what percentage of the workers receive wages between $20 and $23.50?In a random sample of 320 cars driven at low altitudes, 50 of them exceeded a standard of 10 grams of particulate pollution per gallon of fuel consumed. In an independent random sample of 135 cars driven at high altitudes, 17 of them exceeded the standard. Can you conclude that the proportion of high-altitude vehicles exceeding the standard is less than the proportion of low-altitude vehicles exceeding the standard? Let p1 denote the proportion of low-altitude vehicles exceeding the standard and p2 denote the proportion of high-altitude vehicles exceeding the standard. Use the =α0.10 level of significance and the P -value method with the TI-84 Plus calculator. please state all steps to the p method clearly!
