The box plots show the distributions of daily temperatures, in °F, for the month of January for two cities. Which statements are true about the distributions? Check all that apply. Both distributions are symmetric. Both distributions are skewed right. Both distributions are skewed left. The mean and standard deviation would be the best measures to compare the data. The median and IQR would be the best measures to compare the data.

Both distributions are skewed right. The median and IQR would be the best measures to compare the data.

The box plots represent the birth weights, in pounds, of babies born full term at a hospital during one week. Complete the statements to compare the weights of female babies with the weights of male babies. The median female birth weight is _____ the median male birth weight. The range of female birth weight is ______ the range of male birth weight. Which birth weight measure is the same for both genders?

The histogram shows the number of morning customers who visited North Cafe and South Cafe over a one-month period. What is the best measure of center for comparing the number of visitors to the 2 restaurants? What is the best measure of variation for comparing the distribution of the number of visitors to the 2 restaurants? These are the best measures because both distributions are

mean standard deviation symmetrical

The table shows the yearly earnings, in thousands of dollars, over a 10-year period for college graduates. Which statement is true about the distributions representing the yearly earnings? The mean earnings of the self-employed are higher than the mean earnings of the wage earners. The distribution of earnings for wage earners is more symmetric than the distribution of earnings for the self-employed. The IQRs of the distributions are equal. The standard deviations of the distributions are equal.

The distribution of earnings for wage earners is more symmetric than the distribution of earnings for the self-employed.

The table compares the expected outcomes to the actual outcomes of the sums of 36 rolls of 2 standard number cubes. Which comparisons are true of the frequency table? Check all that apply. Both data sets are symmetrical. The mean of the actual sums is more than the mean of the expected sums. The range of the sums is the same for both sets of data. The standard deviation of the actual sums is less than that of the expected sums. The medians and quartiles are the same in both sets.

The mean of the actual sums is more than the mean of the expected sums. The range of the sums is the same for both sets of data. The medians and quartiles are the same in both sets.

The north restaurant can expect to have the same number of morning visitors as the south restaurant. The north restaurant can expect about 55 morning visitors.
