Chapter 3, Problem 3(choose chapter or problem)
Household Winter Temperature 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. Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature. Temperature (F) Frequency 6164 31 6567 67 6869 198 70 195 7172 120 7376 89 7780 50 Source: Based on data from the U.S. Department of Energy
