Suppose that in a sample of 4876customers at a food store, 2654food shop more than once a week. Find a 90% confidence interval for the population proportion of customers who shop more than once a week. Interpret your answer. b) A claim is made that 52% of all customers at a food store shop more than once a week. Using the results from part (a) of this problem, would this claim be valid or invalid?

An FDA officer claims that Pharma XYZ’s new caplet drug contains less than 300mg of paracetamol. Test the claim using 99% confidence level. In each of the situations, answer the following. a. State the null and alternative hypothesis in words. b. State the null and alternative hypothesis in symbols. c. What is the probability of committing type i error? d.

A study shows that men are most likely to say that they feel “fit” if their overall body fat percentage is less than 17%. A 95% confidence interval is given below for µ, the mean body fat percentage of men of various ages. Use the interval to determine the conclusion (reject or fail to reject the null hypothesis) to a hypothesis test of H0: µ = 17 vs Ha: µ < 17. For men in their 20’s, the 95% confidence interval was 11.68 to 16.78. For men in their 30’s, the 95% confidence interval was 15.14 to 20.03.
To test the hypothesis that the proportion of mothers with antenatal depression scores over 13(HighADEP) in the population from which your sample was drawn is different from 0.11, the researchers obtained the following output from SPSS. Notice the output is produced twice. Once with 90% confidence intervals and once with 95% confidence intervals. Based on this output which is the correct statement. Assume α=.05. Group of answer choices: Which one? a) The researchers would conclude that the proportion of mothers with antenatal depression scores over 13(HighADEP) in the population from which your sample was drawn is significantly less than 0.11 since the one-sided 95% confidence interval [−∞, .101] does not contain 0.11 as a plausible value for the population proportion. b) The researchers would conclude that the proportion of mothers with antenatal depression scores over 13(HighADEP) in the population from which your sample was drawn is not significantly different from…
Suppose you surveyed a sample of 100 in state students at public colleges in PA and a sample of 100 in state students at public colleges in Ohio and found that the average difference in tuition between the 2 groups is $2,982, 95% CIs [$1,769, $4,195]. Based on this confidence interval, would you reject or fail to reject the null hypothesis?
A newsgroup is interested in constructing a 99% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 598 randomly selected Americans surveyed, 384 were in favor of the initiative. Round answers to 4 decimal places where possible. a. With 99% confidence the proportion of all Americans who favor the new Green initiative is between ? and ? b. b. If many groups of 598 randomly selected Americans were surveyed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about ? percent will not contain the true population proportion.
We have created a 95% confidence interval for μ with the result (148, 196). What conclusion will we make if we test H0: μ = 190 vs. Ha:μ ≠ 190 at α = 5%? A. Reject the alternative hypothesis B. Reject the null hypothesis C. Fail to reject the null hypothesis D. Type I error
ou are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 352 randomly selected caterpillars observed, 55 lived to become butterflies. Round answers to 5 decimal places where possible. a. With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between ?and .? b. If many groups of 352 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about ? percent will not contain the true population proportion.
