Answer:
H0: p1-p2=0
Ha: p1-p2≠0
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
Step-by-step explanation:
Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .
Ha: p1-p2≠0
The null hypothesis is
H0: p1-p2=0 i.e these data do not provide strong evidence the rate of sleep deprivation is different for the two states.
where p1 = as population 1 of California
p2= as population 2 of Oregon
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
which will also give the same results as above and a two tailed test will be performed for both hypotheses.
Answer:
49% and 30% respectively
Step-by-step explanation:
Step one:
Given data
Principal = Rs. 4,200
Final Amount= Rs. 9282 respectively
time = 2 years and
time = 4 years
Required
The rate of interest for 2 and 4 years
Step two:
the compound interest formula is
A= P(1+r)^t
for 2 years
Substitute
the rate is 49%
For 4 years we have
![1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\](https://tex.z-dn.net/?f=1%2Br%3D%20%5Csqrt%5B4%5D%7B%5Cfrac%7B9282%7D%7B4500%7D%20%7D%20%5C%5C%5C%5C1%2Br%3D%5Csqrt%5B4%5D%7B2.21%7D%20%20%5C%5C%5C%5C1%2Br%3D%201.30%5C%5C%5C%5Cr%3D1.30-1%5C%5C%5C%5Cr%3D%200.30%5C%5C%5C%5C)
the rate is 30%
