Consider the following sample data: 9.37, 13.04, 11.69, 8.21, 11.18, 10.41, 13.15, 11.51, and 7.75. Isit reasonable to assume that this data is a sample from a normal distribution? Draw the normalplot. Is there evidence to support a claim that the mean of the population is 10?4. A computer program has produced the following output for a hypothesis-testing problem:Difference in sample means: 2.35Degrees of freedom: 18Standard error of the difference in sample means: ?Test statistic: to 2.01p-value: 0.0298(a) What is the missing value for the standard error?(b) Is this a two-sided or a one-sided test?(c) If a = 0.05, what are your conclusions?(d) Find a 90% two-sided CI on the difference in means.5. Two types of plastic are suitable for use by an electronic calculator manufacturer. The breakingstrength of this plastic is important. It is known that 0₁ = 02 = 1.0 psi. From random samplesof n₁ = 10 and n₂ = 12 we obtain ỹ₁ = 162.5 and ÿ2 = 155.0. The company will not adopt plastic1 unless its breaking strengths exceeds that of plastic 2 by at least 10 psi. Based on the sampleinformation, should they use plastic 1? In answering this question, set up and test appropriatehypotheses using a = 0.01. Construct a 99 percent confidence interval on the true mean differencein breaking strength.

As per the policy,we will provide the solution of only 1 question .Please post other questions…

A nationwide study of undergraduate students reported that the mean number of drinks consumed per week during the spring semester is 7.96. The mean number of drinks consumed per week at USC is 7.64 (s.d.=2.55, N=412 Health services is concerned that USC students are consuming significantly more alcohol per week than the national average. Using an alpha level of .05, Is there sufficient evidence to be concerned? Be sure to select the correct critical value for the alternative hypothesis, and then use this evidence to make your conclusion
Are seatbelts effective at saving lives? We wish to examine whether or not the use of seatbelts reduces fatalities at the alpha = 0.05 level of significance. Let p N represent the proportion of non-seatbelt wearing passengers who were involved in a crash and died and represent the proportion of seatbelt wearing passengers who were involved in a crash and died. 1. Which would be correct hypotheses for this test?

Consider the following: In general, when people diet they typically lose 10 lbs. (?σ = 2). A random sample of 16 people on the keto diet lost 15 lbs. Do people on the keto diet lose more or less weight than people on diets in general? 4. What is the research hypothesis? a) Weight loss in the keto diet sample does not differ from weight loss in the population of dieters in general (H1: X-bar = Mu) b)Weight loss in the keto diet sample does differ from weight loss in the population of dieters in general (H1: X-bar = Mu) c) Weight loss in the keto diet sample does not differ from weight loss in the population of dieters in general (H1: X-bar does not equal Mu) d) Weight loss in the keto diet sample does differ from weight loss in the population of dieters in general (H1: X-bar does not equal Mu)
