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, whichrepresent the daytime household temperature the thermostat is set to when someone is home for a random sample of 737 households. Determine the class midpoint, if necessary, for each classand approximate the mean and standard deviation temperature.BEE Click the icon to view the frequency distribution for the daytime household temperatureClassClass Midpo61-6465-6768-697071-7273-7677-80(Round to one decimal place as neThe sample mean is °F.(Round to one decimal place as neThe sample standard deviation is(Round to one decimal place as neFrequency distributionTemperature (°F)Frequency61-643465-676868-691937019671-7211773-768477-8045PrintDone-X

How does the mean from the raw data (question 7) compare to the mean from the grouped data (question 9)? Use the frequency chart to create a histogram of the daily high temperatures at Cox-Dayton International Airport for June and July 2018. Describe the distribution by shape, center, and spread. Also, state whether there are any outliers.
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.
