Proctor ts Question 6 ▼ No Comments 0/2 pts 299 Details A study of tipping behaviours examined the relationship between the colour of the shirt worn by the server and whether or not the customer left a tip. Group 1: In a random sample of 70 customers served by a server wearing a red shirt, 45 left a tip. Group 2: In a random sample of 342 customers served by a server wearing a non-red shirt, 195 left a tip. At the 5% level of significance, is there a difference in tip leaving between red-shirted servers and non- red-shirted servers?

Suppose that the number of expensive goods X sold in a shop over 24 days, is Poisson random variable with rate 240, i.e. X Poisson (240), where > 0 is the expected number of sales per day and is the unknown parameter that we would like to estimate. Suppose further that can take three possible values 0₁ = 1/2, 0, 1/4 and 0₁ = 1/8, with prior probabilities 0.2, 0.5 and 0.3, respectively. Suppose now that we observe that x=10 expensive goods were sold in the last 24 days. (a) Write down the likelihood function for and find the MLE of 0. (b) Given the observed data 2 = 10, what is the posterior distribution of 0, p(0 | x= 10)? (c) What is the posterior mean for ? (d) What is the posterior standard deviation for 0? [Hint: You may use the fact if X is a random variable, then var(X) = E(X²) – [E(X)]²].
