Bottles (j. testing eval., 1993: 129—131) includesthe accompanying data on compression strength (lb)for a sample of 12-oz aluminum cans filled withstrawberry drink and another sample filled withcola. strawberry drink: sample size 15, sample mean 540, sample sd 21. cola: sample size 15, sample mean 554, sample sd 15.does the data suggest that the extra carbonationof cola results in a higher average compressionstrength? perform the two-sample t test. what is the test statistic?
