Fast computer: Two microprocessors are compared on a sample of 6 benchmark codes to determine whether there is adifference in speed the times (in seconds) used by each processor on each code are as follows:Code134Processor A 28.9 17.1 21.8 17.6 20.5 26.4Processor B 22.4 18.1 28.9 28.4 24.7 27.5Send data to ExcelPart: 0/ 2Part 1 of 2(a) Find a 98% confidence interval for the difference between the mean speeds. Let d represent the speed of processor Aminus the speed of processor B. Use tables to find the critical value. Carry your intermediate computations to at least 3decimal places. Round your final answers to 2 decimal places.A 98% confidence interval for the difference between the mean speeds is- 10.088

The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than volunteers without training. Let μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. What are the appropriate hypotheses?
Data from a government agency showed that the mean performance rating of employees is 87% with a standard deviation of 10%. Samples of 50 employees’ record were found to have a mean performance of 83. Based on this data, can we say that the mean performance of those employees were below the average at 0.05 level of significance?
A recent study stated that if a person chewed gum, the average number of sticks of gum he or she chewed daily was 8. To test the claim, the researcher selected a random sample of 36 gum chewers and found the mean number of sticks of gum chewed per day was 8. The standard deviation of population is 1. at a = 0. 05, is the number of sticks of gum a person chews per day actually greater than 8. There is not enough evidence to support the claim that average is greater than 8. There is enough evidence to support the claim that average is greater than 8. There is enough evidence to support the claim that average is smaller than 8. There is not enough evidence to support the claim that average is greater than 8.
