Suppose you wish to find out the answer to the age-old question, "Do people prefer Cola 1 or Cola 2?" You conduct a blind taste test in which individuals are randomly asked to drink one of the colas first,followed by the other cola, and then asked to disclose which drink they prefer. Results of your taste test indicate that 59 of 100 individuals prefer Cola 2. Complete parts a through c.(a) Conduct a hypothesis test (preferably using technology) Ho: p = po versus H₁: ppo for po = 0.48, 0.49, 0.50, 0.68, 0.69, 0.70 at the a= 0.05 level of significance. For which values of po do younot reject the null hypothesis? What do each of the values of po represent?Do not reject the null hypothesis for the values of po between(Type integers or decimals. Do not round.)Oandinclusively.

The setup hypothesis is: H0:p=p0 versus H1:p≠p0.The objective is to define the values of p0…

A survey was conducted to investigate trends of romantic relationships and online behaviors. Out of 250 adults in their 20s (20 to 29), 180 reported using social media to check on an ex (someone they used to date / be in a romantic relationship with). Out of 260 adults in their 40s (40 to 49), 156 reported using social media to check on an ex. You will perform a hypothesis test to see if the data provide evidence that there is a difference between the age groups in the proportions of people who checked on an ex. What is the alternative hypothesis? a.The proportion of people in their 20s who used social media to check on an ex is the same as the proportion of people in their 40s who used social media to check on an ex. b. The proportion of people in their 20s who used social media to check on an ex is different from the proportion of people in their 40s who used social media to check on an ex. c. The proportion of people in their 20s who used social media to check on an ex is…
A survey of 1000 adults from a certain region asked, "If purchasing a used car made certain upgrades or features more affordable, what would be your preferred luxury upgrade?" The results indicated that 58% of the females and 51% of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of 600 females, 348 reported window tinting as their preferred luxury upgrade of choice, while of 400 males, 204 reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below. a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the 0.05 level of significance? State the null and alternative hypotheses, where π1 is the population proportion of females who said they prefer window tinting as a luxury upgrade and π2 is the population proportion of males who said they prefer window tinting as a luxury…
A legal researcher was interrested in gender differences in the willingness of prosecutrs to plea bargain. She recorded the number of times they plea bargained out of their last 10 cases for a sample of eight female prosecutors and seven male prosecutors. Table 2 shows the number of plea bargain cases by gender. Females Males 9 4 3 5 5 7 9 4 9 3 5 4 7 3 5 From performing a hypothesis test to determine if female and male prosecutors differ in their plea bargaining of cases what is the p value?
Researchers compared the balance of a sample of elderly (E) patients with that of a separate sample of younger (Y ) patients. They exposed members of each age group to unpredictable noises and measured the amount of forward and backward sway. To test whether the elderly tend to sway more, they should choose which pair of hypotheses?
You are conducting a study to see if the proportion of voters who prefer the Dermocratic candidate is significantly different from 59% at a level of significance of a = 0.05. According to your sample, 35 out of 69 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v|Select an answerv (please enter a decimal) H: ?vSelect an answerV (Please enter a decimal) c. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?va f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly different from 59% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 59%. O The data suggest the populaton proportion…
QUESTION 12 Are beer (B), wine (W), and liquor (L) equally favored by Americans as the alcoholic drink they consume most often? A 2016 Gallup survey interviewed a random sample of American adults about their alcohol consumption and preferences. Of the 647 non-abstainers who answered the question about which beverage beer, wine, or liquor they consume most often, 293 selected beer, 218 selected wine, and the remaining 136 selected liquor. What is the p-value and decision rule for the test using a significance level of 0.05? O p-value = 1.000, we reject Ho. O p-value = 0.000, we reject Ho. O p-value = 1.000, we fail to reject Ho. O p-value = 0.000, we accept Ho-

An advertising agency collected a random sample of 300 businesses targeted with an advertising campaign for a large commercial bank. The sample was used to investigate the efficacy of the advertising campaign. One of the variables measured was whether the business was considering becoming a client of the bank. Of the businesses sampled, 50 of the 300 businesses reported that they were considering becoming a client of the bank. A hypothesis test was conducted to determine if this provides evidence that less than 20% of all businesses were considering becoming a client of the bank. Calculate the test statistic to two decimal places (2dp). Test statistic =
