Often, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise besmall or very large. Consider the following data, which represent the daytime household temperature the thermostat is set to whensomeone is home for a random sample of 740 households. Determine the class midpoint, if necessary, for each class and approximatethe mean and standard deviation temperature.Click the icon to view the frequency distribution for the daytime household temperature.ClassClass MidpointFrequency distribution61-6465-6768–69Temperature (°F)61-64Frequency703465-676471-7268–6919873–767019777-8071-72120(Round to one decimal place as needed.)73–768077-8047
