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 751 households. Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature. E Click the icon to view the frequency distribution for the daytime household temperature. Class Class Midpoint 61-64 65-67 68-69 70 71-72 73-76 77-80 (Round to one decimal place as needed.)

Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below. Compute the relative and cumulative relative frequencies and use a line chart to construct an ogive.   Complete the frequency distribution for the months as a​ customer, and compute the relative and cumulative relative frequencies. ​(Type integers or decimals rounded to three decimal places as​ needed.)
