Step-by-step explanation:
are you trying to work out how many ppl it split between ??
2.1S + 4.8H = 2808
H = 2S
2.1S + 4.8(2S) = 2808
2.1S + 9.6S = 2808
11.7S = 2808
S = 2808/11.7
S = 240
H = 2S
H = 2(240)
H = 480
so the standard version (S) has 240 downloads and the high quality version (H) has 480 downloads
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.
