These injuries were further classified as " accidental" if caused by dropped weight or improper equipment use. Of the 4094 weight-lifting injuries, 1681 were classified as accidental.
What is a 95% confidence interval for the proportion of weight-lifting injuries in this age group that were accidental?
The 95% confidence interval (±±0.001) is from to

7.40 People were asked whether they agreed or disagreed with the statement that there is only one true love for each person. The table below gives a two-way table showing the answers to this question as well as the education level of the respondents. A person’s education is categorized as HS (high school degree or less), Some (some college) or College (college graduate or higher). Is the level of a person’s education related to how the person feels about one true love? If there is a significant association between these two variables, describe how they are related.

Use the cumulative normal probability excel output above (dealing
with the amount of money parents spend per child on back-to-school
items) to answer the following question.
The probability is 0.38 that the amount spent on a randomly
selected child will be between two values (in $) equidistant from
the mean. The lower of these equidistant points is provided in the
excel output above. Use the lower endpoint and some math to find
the upper endpoint.
