Vegetarian and plant-based options are becoming more widely available in restaurants and grocery stores. A survey is conducted to determine the percentage of adults in the United States who declared themselves to be vegetarian. The 95% confidence interval for the percentage of adults who declared vegetarian is (0.068, 0.129). Complete parts a and b. a. Interpret the meaning of this confidence interval using a complete sentence.   b. Use StatCrunch to find the sample size required to estimate the percentage of adults in U.S. who declare themselves to be vegetarian: assume no prior studies were made and we need to be within an error of 3%?

The following is a probability distribution of the number of cars (X) owned by 120 residents who live in the same neighborhood. Use StatCrunch to find the mean and standard deviation of the number of cars owned by the 120 residents.  X (Number of Cars)  1  2  3  4  5  P(X)  0.01  0.33  0.36  0.22  0.08

Statsville Credit Union is considering switching from having multiple lines (one for each teller) to having one single line for all tellers. They recorded a random sample of customer wait times (in seconds) using each method.  Multiple Lines:   248   313   354   371   405   455   449   508   543   603 Single Line:         379   394   406   400   430   432   414   450   461   461          Use StatCrunch to find the mean and standard deviation of the times using each method.  Based on these data, which method appears to be better?

There is always a need for people to donate blood. College students often volunteer when there are blood drives on campus. A survey is conducted to determine the percentage of students who have a negative blood type (O-, A-, B- or AB-) as they exit the bloodmobile. The 95% confidence interval for the percentage of students who reported a negative blood type is (12.4%, 17.7%). Complete parts a and b. a.) Interpret the meaning of this confidence interval using a complete sentence.   b.) Use StatCrunch to find the sample size required to estimate the percentage of students who reported a negative blood type.  Assume no prior studies were made and we need to be within an error of 3%. 

A player must cross 10 hurdles in a hurdle race. The probability that he will clear each hurdle is 0.86. Use StatCrunch to find the probability that he will clear more than 7 hurdles.
