Suppose it is known that a company completes a certain type of order in average of 48 minutes with a standard deviation of 15 minutes, and that for a second type need 30 minutes long with a standard deviation of 20 minutes. If a manger randomly observes 35 from the first type and 40 from the second type, what is the probability that the average time to complete the task of the type 1 will be more than 20 minutes from the type 2? 0.3121 0.0003 0.1093 0.9654

The human resources department of a consulting firm gives a standard creativity test to a randomly selected group of new hires every year. This year, 100 new hires took the test and scored a mean of 113.6 points with a standard deviation of 134. Last year, 95 new hires took the test and scored a mean of 116.4 points with a standard deviation of 16.8. Assume that the population standard deviations of the test scores of all new hires in the current year and the test socores of all new hires last year can be estimated by the sample standard deviations, as the samples used were quite large. Construct a 90 confidence interval for the difference between the mean test score , of new hires from the current year and the mean test score , of new hires from last year. Then tind the lower limit and upper limit of the 905% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answeis to at least two decimal places.

Group A has 12 people and it is a random sample and they have an average heart rate of 100 and their standard deviation is 5. Group B has 18 people and their average heart rate is 90 and they have a standard deviation of 6. do these sample statistics provide sufficient evidence at a=0.01 to claim that the average heart rate for the population of group A is statistically greater than the heart rate of the population of group B?

Suppose a manufacturer produces light bulbs and claims that their average lifespan is 1000 hours with a standard deviation of 100 hours. If a random sample of 50 light bulbs is taken, what is the probability that the average lifespan of the sample will be greater than 1050 hours? And how does this probability change if the sample size is increased to 100?
A psychologist obtains a random sample of 20 mothers in the first trimester of their pregnancy. The mothers are asked to play Mozart in the house at least 30 minutes each day until they give birth. After 5 years, the child is administered an 1Q test. It is known that IQs are normally distributed with a mean of 100. If the IQs of the 20 children in the study result in a sample mean of 104.4 and sample standard deviation of 16, is there evidence that the children have higher IQs?
