Answer:
-32+y+90
y=122
Step-by-step explanation:
A. T. S.A =2* AREA OF TRIANGLE +PREIMETER*5.56
VOLUME=AREA OF *LENGTH[ 5.56]
B. T. S. A=πR{R + SLANT HIGHT }
VOLUME=1/3*π*R*HIGHT{ 7 }
volume of a sphere is 3 by 4 by R cube and surface area of a sphere is 4 Pi R Square
Answer:
D)Yes, because the difference in the means in the actual experiment was more than two standard deviations from 0.
Step-by-step explanation:
We will test the hypothesis on the difference between means.
We have a sample 1 with mean M1=18.2 (drug group) and a sample 2 with mean M2=15.9 (no-drug group).
Then, the difference between means is:

If the standard deviation of the differences of the sample means of the two groups was 1.1 days, the t-statistic can be calculated as:

The critical value for a two tailed test with confidence of 95% (level of significance of 0.05) is t=z=1.96, assuming a large sample.
This is approximately 2 standards deviation (z=2).
The test statistict=2.09 is bigger than the critical value and lies in the rejection region, so the effect is significant. The null hypothesis would be rejected: the difference between means is significant.
