Question

4. A study includes the accompanying data on compression strength (lb) for a sample of 12-oz aluminum cans filled with strawberry drink and another sample filled with cola. Does the data suggest that the extra carbonation of cola results in a higher average compression strength? Test at ? = .05. Sample St. Sample Mean 546 560 Beverage Sample Size Strawberry drink Cola 15 15 Dev. 21 15

Answer 1

here as test statisitc falls in rejection region we reject null hypotheiss

we have sufficient evidence to conclude that extra carbonation of cola results in a higher average compression strength.
