At a magic shop, the salesperson shows you a coin that she says will land on heads more than 73% of the times it is flipped. In an attempt to convince youshe's correct, the salesperson asks you to try the coin yourself. You flip the coin 60 times. (Consider this a random sample of coin flips.) The coin lands on heads47 of those times.Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the salesperson's claimthat the proportion, p, of all times the coin lands on heads is more than 73%.(a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test.O 10 under the assumption that the null hypothesis is true.) Heren is the sample size and p is the population proportion you are testing.olo (d) Based on your answer to part (c), choose what can be concluded, at the 0.05 level of significance, about the claim made bythe salesperson.O Since the value of the test statistic lies in the rejection region, the null hypothesis is rejected. So, there is enoughevidence to support the claim that the coin lands on heads more than 73% of the times it is flipped.O Since the value of the test statistic lies in the rejection region, the null hypothesis is not rejected. So, there is notenough evidence to support the claim that the coin lands on heads more than 73% of the times it is flipped.O Since the value of the test statistic doesn't lie in the rejection region, the null hypothesis is rejected. So, there isenough evidence to support the claim that the coin lands on heads more than 73% of the times it is flipped.O Since the value of the test statistic doesn't lie in the rejection region, the null hypothesis is not rejected. So, there isnot enough evidence to support the claim that the coin lands on heads more than 73% of the times it is flipped.

Use the following information to answer the next four problems: In an experiment, 1919 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy, which is a surprising action. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 105 seconds with a standard deviation of 195 seconds. State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let…
An instructor at a major research university occasionally teaches summer session and notices that there are often students repeating the class. Out of curiosity, she designs a random sample of students enrolled in summer sessions and counts the number repeating a class. She counts 105 students in the sample, of which 19 are repeating a class. She hypothesizes that, in general, more than10% of students repeat a course. The hypotheses to be tested are: Select one: H0:p=0.1 vs. Ha:p=0.18 H0:p=0.1 vs. Ha:p≠0.1 H0:p=0.1 vs. Ha:p>0.1 H0:p=0.1 vs. Ha:p>0.18

An anger-management course claims that, after completing its seminar, participants will lose their tempers less often. Always a skeptic, you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.01 level of significance assuming that the population distribution of the paired differences is approximately normal. Let participants before completing the anger-management course be Population 1 and let participants after completing the anger-management course be Population 2.

Hospital floors: Hospital floors are usually bare tiles instead of carpet. Carpets will decrease noise but might increase germ growth. To study this, researchers installed carpet in 8 of 16 hospital rooms. They randomly selected the rooms to carpet. The other rooms had bare tiles. After two weeks of normal use, they collected air samples from the rooms and counted the bacteria in each sample. Based on this description of the experiment, which of the following is a part of the experiment design? Check all that apply. Group of answer choices
You may need to use the appropriate technology to answer this question. A sample of 15 consumers provided the following product ratings for three different products.

Product A BC 54 84 64 67 90 40 70 92 34 42 85 52 60 94 55 Use the Kruskal-Wallis test and a = 0.05 to determine whether there is a significant difference among the ratings for the products. State the null and alternative hypotheses. O H,: Median, + Median, + Median. H3: Median, = Mediang = Medianc O Ho: All populations of product ratings are identical.

Refer to the following scenario. A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 120 people living in Gastown and finds that 21 have an annual income that is below the poverty line. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of Gastown residents living below the poverty line. A. 17.50% (21/120) of Gastown residents are living below the poverty line. ? B. There is a 95% probability that the true proportion of Gastown residents who are living below the poverty line equals 21/120. C. If another random sample of 120 Gastown residents is drawn, there is a 95% probability that the sample proportion of Gastown residents who are living below…
