A real estate company is interested in testing whether, on average, families in Gotham have been living in their current homes for less time than families in Metropolis have. Assume that the two population variances are equal. A random sample of 100 families from Gotham and a random sample of 150 families in Metropolis yield the following data on length of residence in current homes.

Gotham: G = 35 months, sG2 = 900 Metropolis: M = 50 months, sM2 = 1050


Referring to Table 10-4, suppose α = 0.10. Which of the following represents the result of the relevant hypothesis test?

Group of answer choices

A) The alternative hypothesis is rejected.

B) The null hypothesis is not rejected.

C) The null hypothesis is rejected.

D) Insufficient information exists on which to make a decision.

Suppose that a pharmaceutical company is interested in testing their new cholesterol medication and recruited 11 sets of identical twins with high blood pressures. For each twin, one was given the new drug and the other was given the old drug, then the reduction in LDL cholesterol level (unit: mg/dL) was measured after 6 months. Summary statistics of the amount of reduction are shown below. NOTE: Not all outputs given above are useful      n           x           s      New Drug    11    42...

From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters. An environmentalist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each. The sample mean and standard deviation were calculated to be 276 meters and 20 meters respectively....
