Oten, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise be small or very large. Consider the folowing data, which represent the daytime household temperature the thermostat is set to when someone is the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature E home for a random sample of 749 households. Determine T. Click the icon to view the frequency distribution for the amount of savings.
