The hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis Ho and the alternative hypothesis #, that we would use for this test H. : 1 The actuaries of the company claim that the standard deviation of the number of accidents per day is no longer equal to 0.04. Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis Ho and the alternative hypothesis A, that we would use for the actuaries of the company claim that the variance of the nu of accidents per day is no longer equal to 0.0025. Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim. State the nul hypothesis Ho and the alternative hypothesis #, that we would use for this test. H: 0 on time of this minutes. The standard deviation minutes . To test this claim , a random sample of 12 completion times under new minutes. Assume that the population is normally distributed. Can we support, at the 0.05 level of significa time under new management is less than 14.4 minutes? Assume that the population standard deviation of completion times has not changed under new Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (8) state the null hypothesis Ho and the alternative hypothesis H1. H :D H, :0 (b) Determine the type of test statistic to use.

OYes O No The actuaries of the company claim that the standard deviation of the number of accidents per day is no longer equal to 0.05. suppose that we want to carry test. out a hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis Ho and the alternative hypothesis #, that we would use for this Ho: 0 . According to a report done by S & J Power, the mean lifetime of the light bulbs it manufac this by selecting 27 bulbs at random. For the bulbs in the sample, the mean lifetime is 43 months. It is known that lifetimes is 9 months. Assume that the population is normally distributed. Can we conclude, at the 0.10 level of significance, that the population mean lifetime. $4, of light bulbs Perform a two-called test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (2) State the null hypothesis Ho and the alternative hypothesis H1.

The standard deviation of these scores is 36. A special preparation course claims that the mean SAT score, H. of its graduates is greater than $58. An Ind mathematics for the sample was $69. At the 0.05 1 wel of significance, can we conclude that the population mean SAT score for graduate greater than $587 Assume that the population standard deviation of the scores of course graduates is also 36.
