Can you please help with all 3 parts of this question: To test for a relationship between gender and souvenir shopping, a survey of more than 2,000 tourists was conducted. One question asked how often a tourist purchases photographs, postcards, or paintings of the region visited. Responses were recorded as “always”, “often”, “occasionally”, or “rarely or never”. The table shows the number of tourists responding in each category by gender. Male Female Aways 275 445 Often 420 500 Occasionally 390 425 Rarely or never 305 230 a. Give the marginal distribution of responses. b. Give the conditional distribution of responses for each gender. Do you think there is a relationship between gender and souvenir purchase frequency? c. Test for a relationship between gender and souvenir purchase frequency at a significance level of 0.1.
A pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales during the last 15 days were Day: Number 1 3 8 sold: 33 36 37 44 41 45 46 44 48 Day: Number 10 11 12 13 14 15 sold: 49 44 45 45 53 52 a. Assume the data refer to demand rather than sales. Using trend-adjusted exponential smoothing with an initial forecast of 44 for Day 8, an initial trend estimate of 2, and a = B = 3, develop demand forecasts for Days 9 through 16. Then compute the resultant MSE using the error values from Days 8 through 15. (Round your intermediate period-by-period forecast and error values to 3 decimal places. Round your final MSE answer to 3 decimal places.) MSE
A new cold medication claims that, on average, individuals who take the medication recover within 5 days. Dr. Nelson believes the recovery time is longer. She surveys 31 people with colds who take the medication. She finds that their recovery time, in days, is as follows: 7, 5, 4, 8, 5, 5, 4, 4, 5, 5, 6, 4, 4, 5, 4, 7, 5, 7, 4, 6, 4, 3, 5, 7, 8, 4, 7, 4, 6, 4, 6 Perform a hypothesis test using a 9% level of significance. Step 1: State the null and alternative hypotheses. H.: pv >v (So we will be performing a right-tailed Vv test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are t-distributed v with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P( 2v = P(tv 2v %3D p-value = Step 4: Make a Conclusion About the null hypothesis. Since the p-value = = a, we do not reject the…

An experiment investigated the effect of length and repetition of TV ads on students choosing to eat at Del Taco. All 60 students watched a 40-minute television program that included ads for Del Taco. Some students saw a 30-second commerical; others a 90-second commerical. The same commerical was shown either 1, 3, or 5 times during the program. After the viewing, each student was asked to rate their craving for Del Taco on a scale of 0 to 10. What are the subjects of this experiment?A. 60 studentsB. effect of length and repetion of TV adsC. 40-minute television programD. craving for Del Taco on a scale of 0 to 10E. 1, 3, or 5 commercials during the 40-minute television program
