A random survey of 5000 businesses was conducted by Statistics Canada. They reported an average of 8.98 bankruptcies per 1000 businesses from 1999 to 2005 with a standard ERROR of 1.25. Construct a 95% confidence interval for the mean number of bankruptcies per 1000 businesses between 1999 and 2005.
12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren’t happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level.
Suppose you work for the Department of Environment and National Resources (DENR). You want to estimate, with 95% confidence, the mean length of all tilapia in a fish hatchery pond. You take a random sample of 10 tilapia and determine the average length is 10.5 inches and the sample standard deviation is 2.9 inches. Construct a confidence interval for this sample and interpret the result.
56.A random sample of 40 companies with assets over $10 million was surveyed and asked to indicate their industry and annual computer technology expense. The ANOVA comparing the average computer technology expense among three industries rejected the null hypothesis. The Mean Square Error (MSE) was 195. The following table summarized the results: Based on the comparison between the mean annual computer technology expense for companies in the tax service and food service industries, the 95% confidence interval shows an interval of -5.85 to 14.85 for the difference. This result indicates that _______________. A.There is no significant difference between the two industry technology expenses B.The interval contains a difference of 20.7 C.Companies in the food service industry spend significantly more than companies in the tax service industry D.Companies in the food service industry spend significantly less than companies in the tax service industry
