Below is a contingency table from the results of the 2012 General Social Survey. Respondents were asked to identify how much they understood issues facing the country. Responses were broken down by gender.   1:None 2:A little 3:Some 4:Quite a Bit 5:A great deal Male 14 51 140 89 23 Female 16 69 138 58 16   What is the conditional probability that someone knows “a little” given that they were female?

A regression line was found to predict Foreign direct investment (FDI) (net inflows (% of GDP)) based on year for the Lower middle income. The value of R-squared was 0.709. Interpret R-Squared (if applicable).

The body weight of male college athletes has a mean of 181 pounds. The values go from 121 to 229 pounds.Assume that the data is normally distributed.  Which of the following is a plausible value for the standard deviation?

Which of the following is a discrete quantitative variable about tomatoes grown in a garden?

Does someone’s current age affect what they think is an appropriate retirement age? People were polled about both their current age and what they thought would be an appropriate retirement age. They wanted to predict the “appropriate retirement age” by using their current age. The data below is only for female participants.   The average of current age was 33.15 and the standard deviation was 13.93 . The average of appropriate age of retirement was 62.07 and the standard deviation was 8.10. The value for correlation was 0.1616 .   Find the least squares regression equation.

Tests for allergies can be done in multiple ways. One way is through a blood test. ImmunoCAP is one of such tests. About 0.5% of adults have tree nut allergies at some level of severity. The test correctly identifies 94% of the time adults with a tree nut allergy and correctly identifies those without tree nut allergies 93% of the time.   What is the probability of an adult having a tree nut allergy and the test being positive?

The below stem and leaf plot states the sepal (a part of the flower – usually green) width(cm) of a sample of 150 irises.     What is the minimum sepal width?

A survey was conducted of college students in the US. They were asked to give their own height as well as the height that they would like their mate to be. Below is the least squares regression output for this data. The output below was conducted on only the male respondents. What is the predicted height for a mate of a 58 inch tall respondent?
