The mean weight of 20 randomly selected newborn babies at a local hospital is 7.68 lbs and the standard deviation is 0.7 lbs. Assume the weight of newborn babies has approximately normal distribution. (a) Find the margin of error for the 99% confidence interval for the mean weight of all newborn babies at this hospital. (Round your answer to two decimal places.) (b) Use information from part (a) to fill in the banks in the following sentence: % of all samples of size have sample means within Ibs of the population mean. (c) Find a 99% confidence interval for the mean weight of all newborn babies at this hospital. (Round your answer to two decimal places.) Ibs <μ< Ibs (d) Does the confidence interval, at 99% level, provide sufficient evidence that the mean weight of a newborn atthis hospital is above 6 lbs? Write the appropriate inequality to justify your answer

In the past, the mean age of consumers of a product was 38 years. Recently the product has been drastically changed. In order to determine whether there has been a change in the mean age of the product consumers, a sample of 16 consumers is selected. The mean age in the sample is 33 years and the standard deviation in the sample is 10 years. Let u = the mean age of the current product (Problem Set #7) consumers.
