How would I solve 1 1 Moore Travel a nationwide travel agenc

1) Moore Travel, a nationwide travel agency, offers special rates on certain Caribbean cruises to senior citizens. The president of Moore Travel wants additional information on the ages of those people taking cruises. A random sample of 40 customers taking a cruise last year revealed these ages: (Organize the data into a frequency distribution, using 7 classes and 15 as the lower limit of the first class) 77 18 63 84 38 54 50 59 54 56 36 26 50 34 44 41 58 58 53 71 51 62 43 52 53 63 62 62 65 61 52 60 60 45 66 83 71 63 58 61 Classes RF CRF (a) If you have to spend marketing funds for a certain age group, based on this data, on what age group would you spend your budget? 2) The local manager of Food Queen is interested in the number of times a customer shops at her store during a two-week period. The responses of 51 customers were: (Complete the distribution) 5 3 3 1 4 4 564 2 6 6 6 7 1

Solution

From a random sample of 40 we have to prepare frequency distribution.

For that it is given that lowest class limit starts from 15.

First find out the minimum and maximum from the data.

Minimum = 18 and maximum = 84

Range = 66

As there are 7 classes, we can give class interval width as 10

i.e. 15-<25, 25-<30 etc.

Use tally marks method to find the frequency. i.e. if first item is 77, put a back slash in 75-<85 row, etc.

Finish this process for all so that we can count the back slashes to find the frequency.

Hence frequency distribution is:

----------------------------------------------------------------

a) From the table we observe maximum frequency is for age group 55-65, and minimum frequency is for 15-25

Hence spend marketing funds for 15-25 group to get more people by making aware of this and get more customers.
