For this case we have the following expression:
 (6.21 + 0.93) + 0.07
 We apply the associative property of the addition to rewrite the expression.
 This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.
 We have then:
 6.21 + (0.93 + 0.07)
 Answer:
 
6.21 + (0.93 + 0.07)
 
Associative property.

Answer:

Since 95% confidence interval contains 0 we conclude at 95% confidence level that the two means are equal.

Step-by-step explanation:

Given that in a  fast food study a researcher finds that mean sodium content of 32 Wendy's fish sandwiches is 1080 milligrams with a standard deviation of 75 milligrams. The mean sodium content of 39 Long John Silver's fish sandwiches is 1120 milligrams with a standard deviation of 100 milligrams

H0: The two means are equal

Ha: The two means are not equal

(Two tailed test at 5% level)

Variable A Variable B

Mean 1080.00 1120.00

SD 75.00 100.00

SEM 13.26 16.01

N 32 39

95% CI: -82.65 to 2.65

Since 95% confidence interval contains 0 we conclude at 95% confidence level that the two means are equal.
