A random sample of 140 births from local records shows this distribution across the days of the week: \begin{tabular}{|l|c|c|c|c|c|c|c|} \hline & Sunday & Monday & Tuesday & Wednesday & Thursday & Friday & Saturday \\ \hline Count & 13 & 23 & 24 & 20 & 27 & 18 & 15 \\ \hline Expected \\ Value & 10.769 & 6.086 & 5.833 & x & 5.185 & 7.778 & 9.333 \\ \hline \end{tabular} a) Find the expected values if births were evenly distributed throughout the week, and enter them into the chart above. Which days of the week appear to have fewer births than expected? \text{All of them}.

Step 1: To find the expected value for each day, we divide the total number of births (140) by the number of days in a week (7). Show more…

Use the given categorical data to construct the relative frequency distribution. Natural births randomly selected from four hospitals in a highly populated region occurred on the days of the week (in the order of Monday through Sunday) with the frequencies 52, 63, 68, 58, 60, 45, 54. Does it appear that such births occur on the days of the week with equal frequency? Construct the relative frequency distribution. Day Relative Frequency Monday % Tuesday % Wednesday % Thursday % Friday % Saturday % Sunday % (Type integers or decimals. Round to two decimal places as needed.)

A researcher wants to determine whether children are more likely to be born on certain days of the week. She will sample 315 births and record the day of the week for each. The null hypothesis is that a birth is equally likely to occur on any day of the week. Compute the expected frequencies. Day Monday Tuesday Wednesday Thursday Friday Saturday Sunday Expected Births

Use the given categorical data to construct the relative frequency distribution. Natural births randomly selected from four hospitals in a highly populated region occurred on the days of the week (in the order of Monday through Sunday) with the frequencies 52, 64, 71, 55, 62, 44, 52. Does it appear that such births occur on the days of the week with equal frequency? Construct the relative distribution. Day Relative Frequency Monday __% Tuesday __% Wednesday __% Thursday __% Friday __% Saturday __% Sunday __% (type integers or decimals. Round to two decimal places as needed. )
