(c) Determine the mean number of children. The mean number of children is (Round to two decimal places as needed.) Determine the standard deviation number of children. The standard deviation number of children is (Round to two decimal places as needed.) (d) Explain why a large sample size is needed to perform any inference regarding this population. Choose the correct answer below. O A. The standard deviation is less than the mode. O B. The mean number is greater than the standard deviation. O C. The data are clearly skewed to the right. O D. The data are symmetric. (e) Ten years ago, the ideal number of children was considered to be 2.73. Do the results of this poll indicate that people's beliefs as to the ideal number of children have changed? Use a = 0.05. Determine the null and alternative hypotheses. Ho: 2.73 children H,: V2.73 children Calculate the test statistic, to- to =0 (Round to two decimal places as needed.) Calculate the P-value. P-value =D (Round to three decimal places as needed.) State the conclusion for the test.
