- Question 2: A company launches two different marketing campaigns to promote the same product in two different regions. After one month, the company collects the sales data (in units sold) from both regions to compare the effectiveness of the campaigns. The company wants to determine whether there is a significant difference in the mean sales between the two regions. Q: Is there a significant difference in the mean sales between the two regions? Use a 5% significance level. (2 points = 0.25x4 parts) Make null and alternative hypothesis for two sample T-test Conduct Two Sample T test and provide a snapshot of results Null: Alternative: Conclusion: Since the p value is (choose one: less / greater) than 5%,arrow_forwardQuestion 3: A marketing agency wants to determine whether different advertising platforms generate significantly different levels of customer engagement. The agency measures the average number of daily clicks on ads for three platforms: Social Media, Search Engines, and Email Campaigns. The agency collects data on daily clicks for each platform over a 10-day period and wants to test whether there is a statistically significant difference in the mean number of daily clicks among these platforms.

- Binomial probability problem: A new teaching method claims to improve student engagement. A survey reveals that 60% of students find this method engaging. If 10 students are randomly selected, what is the probability that: a) Exactly 7 students find the method engaging? b) At least 8 students find the method engaging? (please note that “at least 8” is different from 8) Question 1: Binomial probability of exactly 7 students (1 point) Question 2: Binomial probability of at least eight students (1 point)arrow_forwardStandard normal distribution problem: A company found that the daily sales revenue of its flagship product follows a normal distribution with a mean of $5,000 and a standard deviation of $500. The company defines a "high-sales day" as any day with sales exceeding $5,750. What percentage of days can the company expect to have "high-sales days"? What is the sales revenue threshold for the bottom 10% of days? (please note that 10% refers to the probability/area under bell curve towards the lower tail of bell curve) Question 1: What percentage of days can the company expect to have "high-sales days"?
