Answer:
n = -6
Step-by-step explanation:
2 ( n + 5 ) = -2
First, solve the brackets.
2n + 10 = -2
Now take 10 to the right side.
2n + 10 -10 = -2 - 10
2n = -12
Then divide both sides by 2.
And now you'll the value of n.
n = ( -6 )
Answer:

Answer: No, the means in the two studies significantly is not different at the 95% confidence level.
Step-by-step explanation:
Since we have given that
Study 1,
Mean = 30.8,
Standard Deviation = 6.2,
Sample size = 100
And
Study 2
Mean = 32.2,
Standard Deviation = 5.4,
Sample size = 200
So, Hypothesis would be
So, At 95% confidence level, z = 1.96
So, the test statistic value would be
Since 1.96>-1.9228
So, we will accept the null hypothesis.
Hence,No, the means in the two studies significantly is not different at the 95% confidence level.
