Conduct the hypothesis test and provide the test statistic, critical value and P-value, and state the conclusion.A person purchased a slot machine and tested it by playing it 1,266 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observedoutcomes agree with the expected frequencies, the author obtained a test statistic of y = 21.345. Use a 0.025 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slotmachine appear to be functioning as expected?Click here to view the chi-square distribution table.The test statistic is 2. (Type an integer or a decimal.)The critical value is(Round to three decimal places as needed.)The P-value isO. (Round to four decimal places as needed.)State the conclusion.Ho. ThereV sufficient evidence to warrant rejection of the claim that the observed outcomes agree with the expected frequencies. The slot machineto be functioning as expected.

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.
You want to see if a card dealer is favoring one suit over another. You observe the dealer pick a card, put it back in the deck, shuffle, and then repeat the process 376 times.

A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. When evaluated using the 5% level of significance, what is the decision and interpretation of the null hypothesis? Show all steps.

Brayden tosses a coin 500 times. Of those 500 times, he observes heads a total of 416 times. Calculations show that the probability of this occurring by chance is less than 0.01, assuming the coin is fair. Determine the meaning of the significance level. Select the correct answer below: We expect that 416 of every 500 coin tosses will result in heads. At the 0.01 level of significance, the coin is likely not a fair coin. There is certainty that the coin is not a fair coin.
Zachary works as a quality control engineer at Ford Motor Company. One of his job responsibilities is estimating the proportion of defective engines coming off a production line. The production line setting allows for a defective rate of 5%. In a periodical quality checkup, Zachary selected 100 engines that came off the production line. What is the chance Zachary will find more than 10 defective engines? The corresponding Z score is _____

A local McDonald's manager will return a shipment of hamburger buns if more than 10% of the buns are crushed. A random sample of 81 buns finds 13 crushed buns. A 5% significance test is conducted to determine if the shipment should be accepted. The p value for this situation is:
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
In a survey, 37% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 200 pet owners and discovered that 73 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a = 0.1 level of significance. Because npo (1- Po) 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it 200 times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively: 29, 32, 45, 40, 26, 28. Use a 0.01 significance level to test the claim that the outcomes are not equally likely. Does it appear that the loaded die behaves differently than a fair die? Click here to view the chi-square distribution table. The test statistic is (Round to three decimal places as needed.) The critical value is (Round to three decimal places as needed.) State the conclusion. Ho. There equally likely, so the loaded die sufficient evidence to support the claim that the outcomes are not equally likely. The outcomes to behave differently from a fair die. to be
California Department of Education deems a student to be prepared for college if she scores higher than a certain score on the SAT A survey was conducted looking at 651 students' SAT scores and it was found that 573 students were considered to be prepared for college. Use a 0.10 significance level to test the claim that the proportion of students prepared for college is equal to 80%. Claim: Select an answer v which corresponds to Select an answer v Opposite: Select an answer v which corresponds to Select an answer v The test is: Select an answer v The test statistic is: (to 2 decimals) The p-value is: (to 4 decimals) Based on this we: Select an answer Conclusion There Select an answer v appear to be enough evidence to support the claim that the proportion of students prepared for college is equal to 80%.
