Problem 29BSC

Step1 of 3:

We have the data summarized in the given frequency distribution.

 Age of Best Actress When Oscar Was Won Frequency 20–29 27 30–39 34 40–49 13 50–59 2 60–69 4 70–79 1 80–89 1 SUM N=82

Step2 of 3:

We need to find the mean of the data summarized in the given frequency distribution. Also, compare the computed means to the actual means obtained by using the original list of data values, which areasfoüows: 35.9 years.

Step3 of 3:

consider,

 Age of Best Actress When  Oscar Was Won Frequency(f) x fx 20–29 27 24.5 661.5 30–39 34 34.5 1173 40–49 13 44.5 578.5 50–59 2 54.5 109 60–69 4 64.5 258 70–79 1 74.5 74.5 80–89 1 84.5 84.5 N=82 2939

Where x is the mid value of class intervals and it is calculated by  and so on..

The mean of the data summarized in the given frequency distribution is given by = = 35.8414 35.8

This result is quite close to the mean of 35.9 years found by using the original list of data values.
