Answer:
0.0325
Step-by-step explanation:
3.25% = 3.25 over 100 or,
3.25%=3.25100
3.25 over 100 is the same as 3.25 divided by 100. Completing the division we get:
3.25 ÷ 100 = 0.0325
Therefore, we have shown that
3.25% = 0.0325
Answer:
Step-by-step explanation:
Given that;
Compressed Soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16
Intermediate Soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26
Compressed soil intermediate soil
Mean 2.907 3.286
SD 0.1414 0.2377
Here we have,

The pooled Standard deviation

So standard error for difference in population mean is

by inputting the values we get 0.0623
Degree of freedom for t is
df = 19 + 20 - 2 = 37,
so t-critical value is 2.715.
So required confidence interval for
will be


So required confidence interval is (0.2103 , 0.5483).
