According to a recent marketing campaign, 00 drinkers of either Diet Coke or Diet Pepsi participated in a blind taste test to see which of the drinks was their favorite. In one Pepsi television commercial, an anouncer states that "in recent blind taste tests, more than one half of the surveyed preferred Diet Pepsi over Diet Coke." Suppose that out of those 100, 59 preferred Diet Pepsi. Test the hypothesis, using ?=0.05α=0.05 that more than half of all participants will select Diet Pepsi in a blind taste test by giving the following:

According to a recent marketing campaign, drinkers of either Diet Coke or Diet Pepsi participated in blind taste tests to see which of the drinks was their favorite. In one Pepsi television commercial, an anouncer states that "in recent blind taste tests, at least one half of the surveyed preferred Diet Pepsi over Diet Coke." Suppose that in one of those taste tests, 5050 out of the 120120 participating preferred Diet Pepsi. Test the hypothesis, using α=0.05α=0.05 that at least half of all participants will select Diet Pepsi in a blind taste (hint: take HaHa to be that fewer than half prefer Diet Pepsi) test by giving the following:(a) the test statistic Recall the zz value that marks the start of the rejection region is the critical zz score; if you're lower tailed, it's the zz value that has left area of αα; if you're right tailed, it's the zz value whose area to the right is αα; if you're two-tailed, they're the values of the ±z±z value that −z−z has left area of α2α2 and zz…

The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population. find the p value
An organization published an article stating that in any one-year period, approximately 11.5 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, nine of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult population in the country. At a pre-conceived α = 0.05, what are your following?Decision: , Reason for the decision: ,Conclusion

An organization published an article stating that in any one-year period, approximately 8.2 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, six of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult population in the country. p' = Calculate ?x.

Product ? performed worse in the study because ?% failed to get relief with this product, whereas only ?% failed to get relief with Product ?
In a clinical study, a random sample of 540 participants agree to have their blood drawn, which is to be examined for the presence of antibodies against a certain contagious disease. It is found in 22% of the blood samples, which experimenters hope to extrapolate to the general population. From this random sample, 10 participants' blood samples are selected at random. If X is the number of samples out of the 10 who have these antibodies, what can we say about X? A. The sample size is not large enough for us to approximate X using a normal distribution B.The expected value of X is 22 C. X can be approximated using a normal distribution in lieu of a binomial distribution D. X has a sampling distribution that is normal
A survey of a random sample of 210 male teens and 228 female teens, ages 13 years to 17 years, found that 122 of the male teens and 160 of the female teens brush their teeth at least twice a day. If there is no difference between the proportions in the population of all male and female teens ages 13 years to 17 years who brush their teeth at least twice a day, approximately how many males and females in the sample would be expected to brush their teeth at least twice a day? (A) 105 males and 114 females (B) 122 males and 160 females (C) 135 males and 147 females (D) 141 males and 141 females (E) 219 males and 219 females
31% of all pygmy softshell tortoises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha = 0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?
