Suppose a variable x has population mean μ - 39.45 and standard deviation o = = 2.67. Determine the standard error (SE) of the sampling distribution of the mean of a simple random sample of size n = 12. Give your answer precise to two decimal places. Answer: Check
An airline is considering charging a two-tiered rate for checked bags based on their weight. Before deciding at what weight to increase the rate, the airline wishes to estimate the mean weight per bag checked by passengers. It wants the estimate to be within ±0.25 pounds of the true population mean. A pilot sample of checked bags produced the results shown below. data: 4938384233323437404440364340393649444438 a. What sample size should the airline use if it wants to have 95% confidence? b Suppose the airline managers do not want to take as large a sample as the one determined in part a. What general options do they have to lower the required sample size? The sample size must be at least ???. (Round up to the nearest whole number.) b.

Use the five steps in hypothesis testing. 1. Agriculture: Ground Water Unfortunately, arsenic occurs naturally in some ground water (Reference: UnionCarbide Technical Report K/UR-1. A mean arsenic level of parts per billion (ppb) is considered safe foragricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. Arandom sample of 37 tests gave a sample mean x̄ = 7.2 ppb arsenic, with s= 1.9 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb? Use a= 0.01
