According to the historical data, the life expectancy in Mexico is equal to the life expectancy in Spain. A new study has been made to see whether this has changed, Records of 210 individuals from Mexico who died recently are selected at random. The 210 individuals lived an average of 71.9 years with a standard deviation of 2.9 years. Records of 220 individuals from Spain who died recently are selected at random and independently. The 220 individuals lived an average of 71.1 years with a standard deviation of 2.6 years. Assume that the population standard devlation of the life expectancy can be estimated by the sample standard deviations, since the samples that are used to compute them are quite large. At the 0.01 level of significance, is there enough evidence to support the claim that the life expectancy, u, in Mexico is not equal to the life expectancy, u, in Spain anymore? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H : H, = H2 0. The alternative hypothesis: 口口 The type of test statistic: ロ=ロ The value of the test statistic: (Round to at least three decimal places.) 3.007 The p-value: (Round to at least three decimal places.)
