15.
Yes! You do flip the sign if you are dividing by a negative.
So,
-6x>54

The information is missing. The information is :
Battery Pack model 1 Battery Pack model 2
Sample size 9 9
Sample mean 5 hours 5.5 hours
Standard deviation 1.5 hours 1.3 hours
Solution :
Given :
The null hypothesis is :
The alternate hypothesis is :
Therefore, the standard error is
= 0.66165
Thus the test statics is
= -0.756
6 +(9 -1)²/4×(1/2)⁴
= 6 +8²/4×(1/2)⁴ . . . . . . evaluate parentheses
= 6 +64/4×(1/16) . . . . . . evaluate exponents
= 6 +16×(1/16) . . . . . . . . perform multiplication and divison left to right
= 6 +1
= 7
