- A soda can has a volume of 25 cubic inches. Let x denote its radius and h its height, both in inches. a. Using the fact that the volume of the can is 25 cubic inches, express h in terms of x. b. Express the total surface area S of the can in terms of x.The critical value of t at a given alpha level will be smaller than the comparable critical value of z and is much smaller when n is very small.Do we rejects Ho if the critical value is 1.96 and a calculated Z value is 2.54
- Compute the value of z,determine the critical value of z, and state the decision (reject or do not reject Ho). with solution please.Given that a contingency table has dimensions of 5 * 5 what is the critical value of chi-square at alpha = 0.05Sal knows that parties of people on average spend 75 minutes at their restaurant. They wonder if this average is significantly different on the weekends. They found the average time spent by the 30 parties which dined there this weekend was 82 minutes with a SD of 17 minutes. Assume an alpha of .05. What is the critical value?
