Answer: c. 3.01
Step-by-step explanation:
The test statistic for difference between two population mean (when population standard deviation is known) is given by :
, where 
= Size of first sample
= Size of second sample
= Difference between two sample mean.
= standard deviation for population 1.
= standard deviation for population 2.
As per given , we have
Substitute these values in formula , we get
Hence, the value of the test statistic is <u>3.01</u>.
Hence, the correct option is c. 3.01 .
Solution: X=6
Detailed explanation:
In this problem we're asked to find "x" or the unknown.
The first step is to subtract 11x from both sides.
Next, subtract 79 from both sides.
To finish this off, divide both sides by -11.
Voila! There's our answer!
