Answer:
20.428571
Step-by-step explanation:
C=(22/7)d
C=(22/7)6.5
C=20.428571
Answer: Her answer is wrong because she divided incorrectly. Correct answer: 2
Step-by-step explanation:
PEMDAS
2 to the power of 2=4
3*4=12
12/6=2
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: The number of days would be 7 days.
Step-by-step explanation:
Since we have given that
Variance = 30°
Standard deviation = √30 = 5.47
Mean = 4°
At 95% confidence, z = 1.96
So, number of days that the researcher select to measure the temperature would be

Hence, the number of days would be 7 days.
12 boys, because 4x8=32, and 4x3=12!
