According to the historical data, the life expectancy in Egypt is equal to the life expectancy in Morocco. A new study has been made to see whether this has changed. Records of 200 individuals from Egypt who died recently are selected at random. The 200 individuals lived an average of 63.l years with a standard deviation of 3.2 years. Records of 285 individuals from Morocco who died recently are selected at random and independently. The 285 individuals lived an average of 63.5 years with a standard deviation of 3.1 years. ASsume that the population standard deviation 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 0.1 level of significance, is there enough evidence to support the claim that the life expectancy, u,, in Egypt is not equal to the life expectancy, u, in Morocco 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. The alternative hypothesis: C=C The type of test statistic: (Choose one) v The value of the test statistic: (Round to at least three decimal places.) The p-value: (Round to at least three decimal places.) Continue Submit Assignr O 2021 McGraw-Hill Education, All Rights Reserved Terms of Use Privacy I Acces O Type here to search 99+
