**Transcription for Educational Website:**---**Problem Statement:**A random sample of 480 Oklahoma parents with school-aged children showed that 276 had children doing at least some virtual learning. Find a 97.8% confidence interval for the proportion of all Oklahoma parents who have children doing some form of virtual learning.**Notes:**- Sample size ($ n $) = 480- Number of parents with children in virtual learning = 276- Confidence level = 97.8%**Calculation Details:**- Proportion ($ \hat{p} $) = $ \frac{276}{480} = 0.575 $- Confidence interval = 97.8%---For educational purposes, a teacher may guide students through calculating the confidence interval using the above data and notes.

You are a teacher at a gifted school, and you feel that the newest class of students is even brighter than usual. The mean IQ at your school is 127, and the mean IQ of this new class is 134. In total, there are 32 students in this new class. Also, the standard deviation of the school’s IQ is 8. Use the eight steps to test whether this new class of students is significantly more intelligent than the school’s student body overall.
A survey was conducted in the United States and 10 countries of Western Europe to determine the percentage of teenagers who had used marijuana and other drugs. The results are summarized in the following table. only parts 4-7 iv) Can you spot a country which contributes negatively to the association? If yes, explain how. v) The standard deviation of the percent of teens who have used marijuana is 15.55% and it is 10.24% for the percent who have used other drugs. Calculate the correlation between the percent of teens who have used marijuana and the percent who have used other drugs. Show the ”by hand” formula you may use. vi) What does the correlation coefficient confirm or specify? vii) Do these results allow you to say that marijuana is a ”gateway drug”, that is, that marijuana use leads to the use of other drugs? Explain
Database A contains 40 data items and is made up with an equal number of the values of 0 and 100 and has a mean of 50. Database B also has 40 entries made up equally of the values 49 and51 and also has a mean of 50. Which database will have the smaller value for its standard deviation?
Suppose a normally distributed set of stock prices with 4100 observations has a mean of 114 and a standard deviation of 16. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be between the values 66 and 146. Hint: This problem is asking for how many observations, not the percent. Answer = (Round to the nearest whole observation.)
