The data in photo attached show the number of births per 1000 population in samples taken independently from African and Asian countries. Considering the African countries, test the hypothesis that the standard deviation of the number of births per 1000 population is not equal to 10. Use 0.10 level of significance and assume normality. • State Ho and Ha. • Write the formula of the test statistic to be used. • State the decision rule at 0.10 level of significance. • Compute for the value of the test statistic. • Is there sufficient evidence at 0.10 level of significance to conclude that the standard deviation of the number of births per 1,000 in Africa is not equal to 10?
