Because the null hypothesis is rejected, the week they were born. He finds that 28 babies were born on Sundays, 65 on Mondays, 48 on Tuesdays, 56 on Wednesdays, 45 on Thursdays, 62 on Fridays, and 46 on Saturdays. He tests the following hypotheses: researcher would like to know which term contributed the significance of the test. Complete a follow-up analysis. Which term contributed the most to the significance of this test? Were there more or fewer births on this day than expected? Ho: The distribution of births is uniform across the days of the week. O Sunday, more births than expected O Sunday, fewer births than expected O Monday, more births than expected O Monday, fewer births than expected Hạ: The distribution of births is not uniform across the days of the week.

A researcher would like to investigate if the distribution The chi-square test statistic is x2 = 18.68 and the P- %3D of the number of babies born is uniform across the value is between 0.0025 and 0.005. Because the P- days of the week. To investigate, he selects a random sample of 350 babies and records on which day of the week they were born. He finds that 28 babies were born on Sundays, 65 on Mondays, 48 on Tuesdays, 56 on Wednesdays, 45 on Thursdays, 62 on Fridays, and 46 on Saturdays. He tests the following hypotheses: value is less than 0.05, the researcher rejects the null hypothesis. Because the null hypothesis is rejected, the researcher would like to know which term contributed the significance of the test. Complete a follow-up analysis. Which term contributed the most to the significance of this test? Were there more or fewer births on this day than expected? Họ: The distribution of births is uniform across the days of the week.
