Problem 12BSC

Conduct the hypothesis test and provide the test statistic, critical value, and/or P-value, and state the conclusion. Births?Records of randomly selected births were obtained and categorized according to the day of the week that they occurred (based on data from the National Center for Health Statistics). Because babies are unfamiliar with our schedule of weekdays, a reasonable claim is that births occur on the different days with equal frequency. See the table that follows. Use a 0.01 significance level to test that claim. Can you provide an explanation for the result?

Step-by-Step Solution:

Solution 12BSC Step 1 Given, Births Records of randomly selected births were obtained and categorized according to the day of the week that they occurred, Because babies are unfamiliar with our schedule of weekdays, a reasonable claim is that births occur on the different days with equal frequency. By using 1% level of significance. We are testing Chi-square test (using SPSS). DataWeight casesFrequencies. Then, Descriptive Cross tabs-rows Colour column Result Statistics Chi-squareOK The Output is as shown below 2 Hence, we have = 16.895 with 6 degrees of freedom and P-value = 0.010 at 1% level of significance. (The smaller P-value is, the stronger the evidence against H and in favor of H . If 0 1 P-value is small like 0.01 or smaller, we may conclude that the null hypothesis H is 0 strongly rejected in favor of H . 1 P-value is between 0.05 P-value 0.01, we may conclude that the null hypothesis H is r0ected in favor of H . In ot1r cases, i.e., P-value > 0.05, we may conclude that the null hypothesis H is accep0d) Since P-value is small we reject the null hypothesis at 1% level of significance and conclude that there is no sufficient evidence to claim that births occur on the different days with equal frequency. Here selected births were obtained and categorized according to the day of the week that they occurred because babies are unfamiliar with our schedule of weekdays and hence baby births does not depend upon day of the week since babies are unfamiliar with day of the week.
