(11 pts) A hockey team is convinced that the coin used to determine the order of play is weighted for heads. The team captain steals this special coin and flips it 14 times to evaluate the hypothesis that the coin is weighted for heads, and it shows up heads 12 times. Test this hypothesis (use alpha=.05).
a. (2 pts) What is the appropriate test? b. (1 pt) State the null hypothesis: c. (1 pt) State the alternative hypothesis: d. (2 pts) Find the critical value: e. (1 pt) Calculate the obtained statistic: f. (2 pts) Make a decision: g. (2 pts) What does your decision mean?

For this question, you will flip fair coin to take some samples and analyze them. First, take any fair coin and flip it 12 times. Count the number of heads out of the 12 flips. This is your first sample. Do this 4 more times and count the number of heads out of the 12 flips in each sample. Thus, you should have 5 samples of 12 flips each. The important number is the number of heads in each sample...

A coin was flipped 56 times and came up heads 36 times. At the .10 level of significance, is the coin biased toward heads? (a-1) H0: formula130.mml ? .50 versus H1: formula130.mml > .50. Choose the appropriate decision rule at the .10 level of significance. a. Reject H0 if z >1.282 b. Reject H0 if z < 1.282......... a or b (a-2) Calculate the test statistic. (Carry out all intermediate calculations to at least 4 decimal places. Round your answer...

(23 pts. total) Past experience at Ziggog Travel Agency indicated that 56% of their clients wanted to go to Europe. During the most recent busy season, a sample of 1,000 clients were selected at random and was found that 548 of them were interested in a vacation in Europe. Ziggog management is interested in understanding if there has been a decrease in the percentage of people who want to travel to Europe. Conduct hypothesis testing (with a significance level of...

Question 11 1 pts In 2012, the mean weight of women was reported at 2012 = 162 lbs. Suppose that an investigator hypothesizes that weights are even higher in 2015. She collected a sample of 29 women in the year of 2015, from which she measured a mean weight of 158 lbs with a standard deviation of 10 lbs. An two-tailed alpha level = .05 is applied. Select ALL correct statement(s) below: The investigator aims to compare a sample mean...

An entrepreneur is considering the purchase of a coin operated laundry. The current owner claims that over the past 5 years, the mean daily revenue(u) was $600 with a population standard deviation (a ) of $150. A sample of 30 days (n) reveals a daily mean revenue of $750 (sample mean, X bar), mean revenue is not equal to $600 and assume that the level of significance(a -005) please answer the following questions (20 points) If you were to test...
