The averrage gasoline prrice at Chevvron was $3.12 per gallon lastt month. Due to the recent nation-wide gas price drop, the chiief marketing officer of Chevvron believes that there has been a significant reduction in the average gas pricce. In orrder to test hiis belief, he randdomly selected a sample of 36 of Chevvron gas stations and found the average gas price of these stations was $3.06. Assume that the population standard deviation of the population is $0.12, and the significance level (α) is 5%. A. Formmullate the null and the alternative hypotheses: Null: mu ≤ 3.06; Alternative: mu > 3.06 Null: mu = 3.06; Alternative: mu ≠ 3.06 Null: mu ≥ 3.12; Alternative: mu < 3.12 Null: mu = 3.12; Alternative: mu ≠ 3.12 Null: mu ≤ 3.12; Alternative: mu > 3.12 Null: mu ≥ 3.06; Alternative: mu < 3.06 B. Whatt kind of test is this? (Upper-tailed, lower-tailed or two-tailed test) Upper-tailed Two-tailed Lower-tailed C. Findd the test statistic. Is this a z-score or…
a programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than three percentage points? Complete parts (a) through (c) below. a) Assume that nothing is known about the percentage of computers with new operating systems. n = b) Assume that a recent survey suggests that about 98% of computers use a new operating system.n = c) Does the additional survey information from part (b) have much of an effect on the sample size that is required?

18. The governor of New York has banned selling or purchasing "large" soft drinks, where a "large" is defined as being more than 16 oz. Sonic, famous for its Route 44 drinks is interested in estimating the proportion of New Yorkers that favor this ban. From a random survey of 800 New Yorkers, 375 answered no to the question, “Do you favor the governor's ban on 'large' soft drinks?" a. Find a 97.5% confidence interval for the proportion of New Yorkers who favor the ban on "large" soft drinks. b. Interpret the confidence interval. c. Can you conclude with 97.5% confidence that a majority of New Yorkers favor the ban on "large" soft drinks? Why or why not. d. Without doing any other calculations, can you be 99% confident that a majority of New Yorkers favor the ban on “large" soft drinks?

Determine whether the underlined value is a parameter or a statistic. Telephone interviews of 1,502 adults 18 years of age or older found that only 69% could identify the current vice-president. Is the value a parameter or a statistic? OA. The value is a statistic because the 1,502 adults 18 years of age or older are a population. B. The value is a parameter because the 1,502 adults 18 years of age or older are a population. C. The value is a statistic because the 1,502 adults 18 years of age or older are a sample. OD. The value is a parameter because the 1,502 adults 18 years of age or older are a sample.
