The number of hours spent per week on household chores by all
adults has a mean of 28.6 hours and a standard deviation of 8.8
hours. The probability, rounded to four decimal places, that the
mean number of hours spent per week on household chores by a sample
of 64 adults will be more than 26.75 is:

The table below gives the number of hours spent unsupervised
each day as well as the overall grade averages for seven randomly
selected middle school students. Using this data, consider the
equation of the regression line, yˆ=b0+b1x, for predicting the
overall grade average for a middle school student based on the
number of hours spent unsupervised each day. Keep in mind, the
correlation coefficient may or may not be statistically significant
for the data given. Remember, in practice, it would...
