**Cigarette Smoking Hypothesis Test**A researcher found that a cigarette smoker smokes on average 29 cigarettes a day. She feels that this average is too low. She selected a random sample of 8 smokers and found that the mean number of cigarettes they smoked per day was 30. The sample standard deviation was 2.3. At \(\alpha = 0.10\), is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the critical value method and tables.---**Part 0 / 5**---**Part 1 of 5**(a) **State the hypotheses and identify the claim.**\(H_0\): [Choose one]\(H_1\): [Choose one]This hypothesis test is a [Choose one] test.[Diagram showing options for hypotheses]---**Part 1 / 5**---**Part 2 of 5**(b) **Find the critical value(s).** Round the answer to three decimal places.

genuine answer, upvote guarrantee, no plagarism The Tiny Company manufactures components for word processors. Most of the work is done at the 2000-employee Tiny plant in the midwest. Your task is to estimate the mean and standard deviation of dollar-valued job performance for Assemblers (about 200 employees). You are free to make any assumptions you like about the Tiny assemblers, but be prepared to defend your assumptions. List and describe all of the factors (along with how you would measure each one) you would consider in using standard costing to estimate SDy.

Hypothesis Test is conjectured that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62. A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other 108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62 at the a = .10 level of significance. Which of the following provides both the correct null and the correct alternative hypothesis for this situation? НО: п = 0.62 Ha: π 0.62, Ha::n 0.58 Ha:: π < 0.62
Analysis of variance compares the means of a response variable for several groups. ANOVA compares the variation within each group to the variation of the mean of each group. The ratio of these two is the F statistic from an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom.You intend to conduct an ANOVA with 4 groups in which each group will have the same number of subjects: n=12n=12. (This is referred to as a "balanced" single-factor ANOVA.)What are the degrees of freedom for the numerator?d.f.(treatment) = What are the degrees of freedom for the denominator?d.f.(error) =

ESP People who claim to “have ESP” participate in a screening test in which they have to guess which of sev-eral images someone is thinking of. You and a friend both took the test. You scored 2 standard deviations above themean, and your friend scored 1 standard deviation belowthe mean. The researchers offer everyone the opportunityto take a retest.a) Should you choose to take this retest? Explain.b) Now explain to your friend what his decision shouldbe and why.

Part 1 A population of values has a normal distribution with mean of 50.6 and standard deviation of 98.9. a) Get the z-score for a value of 44. For this problem you use the z score formula b) This z-score tells you how many the score of 44 is above or below the population mean u. c) Find the probability that a randomly selected value is less than 44.

Hypothesis test For a certain nationwide standardized test there are two commonly used preparation products on the market: StudyFocus and Prepara. A researcher in the Education department at a nearby university wants to determine if there is any difference between the two products on the mean score on the test by their users. The researcher obtains the scores on the test from a random sample of 16 users of StudyFocus and a random sample of 14 users of Prepara. (These samples are chosen independently.) These data are shown in the table. ? StudyFocus Prepara Send data to calculator 408, 400, 460, 587, 485, 559, 470, 439, 453, 531, 491, 481, 529, 494, 581, 397 510, 553, 504, 525, 549, 500, 525, 561, 510, 493, 498, 512, 517, 546 V Scores Send data to Excel Perform a two-tailed test.
