What is the probability of having exactly 3 men in the group? c . What is the probability of all the selected people in the group are women? d . What is the

In a large metro area, 78% of workers commute by driving in a car alone. A researcher randomly selects 45 workers from this area and asks how they commute to work. Then, the researcher counts how many drive in a car alone. Can "number who drive in a car alone" in this scenario be considered a binomial random variable? Select the best choice below.

Now that we know about data, we continue our journey with two fundamental descriptive statistics that help us understand fundamental things about a data set.In discussion this week, we are going to explore MEASURES of CENTER, which includes our Mean (aka Average), Median and Mode, and MEASURE of VARIABILITY, which includes Standard Deviation.

To earn full credit for this question, use your own sheet of paper to solve the problem, showing all steps of your work. Approximate the measures of center for following GFDT. Data Frequency 50 - 54 2 55 - 59 1 60 - 64 11 65 - 69 13 70 - 74 20 Report mode and median accurate to one decimal place. Report the mean accurate to two decimal places (or
