d.e.Explain your conclusion to reject or fail to reject the nullhypothesis in terms of p and a.Interpret your conclusion in the context of this problem. 5. Statistical Abstracts (117th edition) reports that the average amount spentannually for food by householders under 25 years of age is $2,690. A randomsample of 16 people under 25 years of age who live in a university neighborhoodwere surveyed. The survey showed that they spent a sample mean amount of$3,220 with sample standard deviation $750. Test the claim that the mean forthis neighborhood is different from the national average. Use a 5% significancelevel. Assume our data is normally distributed.

Given that Sample size n =16 Sample mean=3220 Standard deviation =750

Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 62.87. You want to test this claim. The null and alternative hypothesis in symbols would be: H0:μ=62.87H1:μ≠62.87 The null hypothesis in words would be: The average price of all textbooks from the store is $$ 62.87 Based on a sample of 120 textbooks at the store, you find an average of 71.47 and a standard deviation of 14.2. The point estimate is: _____________(to 3 decimals). The 90 % confidence interval (use z*) is:__________ to __________ (to 3 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis

One of the advantages of understanding statistics is that you can apply the concepts to yourself. This is even easier to do during our present time because of the widespread use of wearables. Wearables are accessory devices or clothing with embedded technology that are worn by a person and used to provide feedback to the person wearing them. Examples include the Fitbit, which is worn on the wrist and gathers data such as number of steps walked, heart rate, sleeping time. Another example is Ambiotex's smart shirt which is designed for athletes and has sensors in the shirt to measure heart rate, anaerobic threshold, fitness and stress levels. There are other companies making similar products. Suppose that you are interested in the amount of sleep you get a night. Sleep is very important and there is evidence that many Americans do not get enough sleep. You hypothesize you get 6 hours of sleep a night. Using a wearable, you track your amount of sleep on 16 random nights. Test the…

In the final step of the backward elimination method, the absolute value of all must be greater than tremove. c. In stepwise regression, to avoid the possibility of removing a predictor variable entered at the same step, we must have tenter tremove.
