Suppose we want to estimate the average speed of cars traveling on Pacheco Pass, and we want to be able to assert with 98% probability that the average error is at most three miles per hour. How large a sample will we need if it can be shown that o = 7.1 mph? 32 cars 30 cars 31 cars

QUESTION 7 When cereal is packaged, the actual amount of of cereal varies from box to box. Suppose a sample indicates that the mean weight of cereal in a 13-ounce box is 13 ounces with a standard deviation of 2 ounces. Use Chebyshev's inequality to find the minimum probability that a box will be within 4 ounces of the mean weight.
Given that x = 35, n = 52, and o = 4, then we can be 95% confident that the true mean,u, lies between the values and
Consider the information above and in question 1. It is conjectured that the mean number of people attending all 2017 Veterans Day celebrations is 145, and of interest is to test this conjecture versus the alternative that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people To test the hypothesis, a simple random sample of 41 Veterans Day celebrations was selected and the number of people attending each was recorded. The mean number of people attending for this sample of 41 celebrations was 157, with a standard deviation of 23 people. The distribution of the data was bimodal. If appropriate, use this information to test the hypotheses stated in question 3 at the a= .05 level of significance. 4 Are the assumptions met? Yes, because there is a simple random sample Yes, because there is a simple random sample and the population is normally distributed Yes, because there is a simple random sample and the sample size is large enough for the…
Scenario: 200 people were asked, “Who is your favorite superhero?” Below are the data. Test the null hypothesis that the population frequencies for each category are equal. α= .05. Iron Man Black Panther Wonder Woman Spiderman fo = 40 fo = 60 fo =55 fo = 45 fe = fe = fe = fe = What is the correct result based on the data?
Which of the following statements are true? There may be more than one true statement; check all that are true. Question 11 options: a) The only reason to carry out an observational study instead of an experiment is if we do not have enough money to run the experiment. b) The variance of the sample mean depends on the sample size and the population variance. c) For large sample sizes, the sample mean will tend to have a normal distribution, whereas for small sample sizes it will tend to have a uniform distribution. d) Randomization can be a useful tool in statistical studies, but only for large sample sizes.

QUESTION 8 Nabisco claims that Chip Ahoy Cookies have an x ̅=28.67 chocolate chips per cookie with a SD=2.67. You randomly select 15 cookies from a new bag and carefully remove all the chocolate chips from each of the 36 cookies. You find the mean of the chocolate chips for the 15 cookies is 24.27 chocolate chips per cookie. Calculate the standard error for the chocolate chips in your experiment. (round to the nearest hundredth).
