###### Question:

wondering how to find the P-value from the data given. I have t-tables and diffewnt tables but not sure how to use them. 3. Some analysts are recommending investment in large oil companies while avoiding investment in small oil companies. To review this claim, the earnings per share for 10 large. international oil companies and 13 small, domestic oil companies are recorded for the past year. A summary of the data is provided in the accompanying table. Do the data support the claim that large oil companies are the better performers? Use a = 0.01, and df oft -20. Large Oil Companies 1 = $6.54 n Small Oil Companies X, =$4.75 = 10 13 = 2.65 sy = 1.85 What is the null and alternative hypothesis? Ho u = Us HA: u, uz What is the test statistic? ts 1-2 5 (9,-1)+31 (0-1) - 6.54 -4.75 (2.65*(10-1)+(1.25) L13-1) 10+13-2 0193726 What is the critical value? (2.528 df = 20 What is your decision? What is the p-value? (Use tables to find)
