Often, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise be small or very arge. Consider the following data, which represent the daytime household temperature the thermostat is set to when someone is home for a andom sample of 725 households. Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation emperature. Click the icon to view the frequency distribution for the daytime household temperature.

Question
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 725 households. Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature. Click the icon to view the frequency distribution for the daytime household temperature. Frequency distribution Temperature (°F) Frequency 61-64 33 65-67 61 68-69 192 70 190 71-72 118 73–76 86 77-80 45
