2. The following data represents the running time of films produced by 2 motion picture companies. Assume these are independent samples Company Time (in minutes) Company 1 102 86 98 109 92 Company 2 81 165 97 134 92 87 114 Test the null hypothesis that the average running time of the films produced by company 2 exceeds the average running time of films produced by company 1 by an amount of 10 minutes. Test against the null hypothesis of a one sided alternative that the difference is more than 10 minutes. Use a .1 level of significance (alpha a) Perform the Hypothesis test at alpha = .1 b) Determine the confidence interval for the difference between the means at 90% CI 7. An engineering statistician wants to conduct a test to determine if there is a difference in the compression strength of two different manufactures of reinforced concrete columns. Each manufacturer has provided sample data for compression strength (column failure) as follows: Manufacturer 1: mean compression strength is 956 KSI based on 30 samples with a standard deviation of 192 KSI. Manufacturer 2: mean compression strength of 898 KSI based on 25 samples with a standard deviation of 256 KSI Conduct a test at alpha equal to .01 to see if there is a difference between the two different manufacturers. Consider the data to be from two different populations.
a) Let X be the number of teams from IU on Pete's season schedule. What's the probability that none of the Pete's opponents are from IU? What distribution and parameter(s) are you using?
Determine the level of measurement for these items related to the newspaper business? The following data gives the weekly amounts spent on groceries for sample of households.
No estimate of the population proportion is available. How large a sample is required?
Suppose that population standard deviation is known to be 10mmHg and samples are from Normal population, test a= 0.01 if blood pressure reading is different from 135mmHg
