Often, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise be small or very large. Consider the following data, which represent the daytime household temperature the thermostat is set to when someone is home for a random sample of 750 households.
A- Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature
Temp (F) Frequency.
61-64 31
65-67 67
68-69 198
70 195
71-72 120
73-76 89
77-80 50
The frequency distribution on the following represent the age of people living in proverty in 2009 (in thousands). In this frequency distribution, the class widths are not the same for each class. Approximate the mean and standard deviation age of a person living in poverty. For the open ended class of 65 and older, use 70 as the class midpoint.
Age Frequency
0-17 15,451
18-24 6071
25-34 6123
35-44 4756
45-54 4421
55-59 1792
60-64 1520
65 and older 3433
