Question

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. )

          Use the given categorical data to construct the relative frequency distribution.

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, 65, 71, 57, 56, 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 nothing% Tuesday nothing% Wednesday nothing% Thursday nothing% Friday nothing% Saturday nothing% Sunday nothing% (Type integers or decimals. Round to two decimal places as needed.) Let the frequencies be substantially different if any frequency is at least twice any other frequency. Does it appear that these births occur on the days of the week with equal frequency?

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, 65, 68, 56, 61, 46, 52. 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 % Let the frequencies be substantially different if any frequency is at least twice any other frequency. Does it appear that these births occur on the days of the week with equal frequency? A. No, it appears that births occur on the days of the week with frequencies that are substantially different. B. Yes, it appears that births occur on the days of the week with frequencies that are exactly the same. C. Yes, it appears that births occur on the days of the week with frequencies that are about the same. D. It is impossible to determine with the given information.

Transcript

00:01 We have been given some data and we want to turn it into a relative frequency distribution.
00:06 So we need a column for the categories.
00:11 So it's our monday, tuesday, wednesday, thursday, saturday, and make some space, sunday.
00:23 Then we need a column for the frequencies and those have been given to us.
00:36 So the frequencies are 52, 64, 71, 55, 62, 44 and 52.
00:49 So these are the numbers of babies born on each of these days.
00:53 How do we turn it into relative frequency? so the relative frequency is equal to the frequency divided by n, the number of pieces of data.
01:04 What is n here? well, all we need to do is add up these frequencies, and we will get the total number of babies born in this week.
01:12 So i'm just adding these up to get 400.
01:20 And this formula gives the proportion.
01:25 So this gives the proportion, and that's in decimal form.
01:32 It tells you the proportion of the babies born on each day...
