Question

Please show all the steps for the table so I know how to do it. I don't understand any of it not even how you get the class sizes and such.

The number of families who used the Minneapolis YWCA day care service was recorded during a 30-day period. The results are as follows 40 35 54 26 57 39 31 49 19 62 2445 37 52 23 43 35 51 65 51 18 63 60 41 42 50 56 4 54 a. Construct a cumulative frequency distribution of this data. (Round your calculated class interval up to the nearest multiple of 5.) Class Cumulative Frequency Less than Less thar Less than Less thar Less than b. How many days saw fewer than 30 families utilize the day care center?

Explanation / Answer

Lowest data value = 4

Highest data value = 65

Number of classes = 5

So,

Approx class width = (65 - 4)/5 = 61/5 = 12.2

Since we need to round it off to the nearest multiples of 5, the class widths will be 15. Now, we just need to count the values which falls under each class.

The table will be:

b) Nuumber of days saw fewer than 30 families utilize the day care center = 6

Class Frequency Less than 15 1 Less than 30 6 Less than 45 15 Less than 60 26 Less than 75 30
