help finding avg outcomes b 1 hat and t test
HOW TO FIND avg observed outcome for treated and untreated as well as calculating B1hat and a t test to evaluate! A randomized experiment on the effects of advertisement on purchases of a product selected a group of 40 customers. 20 of these customers were randomly assigned to the advertisement and the remaining 20 customers were randomly assigned to the control group with no advertisement. Let Yibe the observed outcome for customer i. If customer i bought the product then Yi = 1, otherwise Y = 0. Similarly, let D be the treatment status for customer i. If customer i was assigned to treatment then D = 1, otherwise Di = 0. The sales department tells you that the proportion of customers who bought the product among those that were exposed to the advertisement was double the proportion of the customers that bought the product among those that were not exposed to the advertisement. You also know that V ((1)) = 0.012 and V (y(0)) = 0.01050. What is the average observed outcome for the treated and untreated Let B1 hat be the coefficient of D; in the regression of Y on the treatment indicator. Calculate B1 hat Compute a t-test to evaluate the null hypothesis that the average treat- ment effect is different from zero. Clearly state the null and alternative hypotheses, the test statistic, the test's significance level and whether you reject or not the null hypothesis.
