Answer: 2.50
Step-by-step explanation: you would divide the cost by the amount so 35 divided by 14.
Answer: 
of an hour.
Step-by-step explanation:
1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)
2. Therefore, you must make the following addition:
This is 78 minutes out of 1 hour (60 minutes).
3. Therefore, you have the following fraction:
4. Now, you must reduce the fraction:
5. The answer is 13/10 on an hour.
Answer:
22
Step-by-step explanation:
15-(-7)
15+7=22
Answer:
Since the calculated value of z= 1.6279 does not fall in the critical region Z ≥ ±1.96 we conclude that there is no difference between the population variance and the sample variance.
Step-by-step explanation:
The data given is
Population mean μ= $ 7.18
Population variance= σ²= 3.81
Population Standard Deviation = √σ²= √3.81= 1.952
Sample Mean= x`= $ 8.02
Sample Standard Deviation =s = $ 2.08
Sample Size = 15
Significance Level = ∝= 0.05
The null and alternate hypotheses are
H0: σ1=σ2 against the claim that Ha: σ1≠ σ2
where σ1 is the population variance and
σ2 is the sample variance
The rejection region is Z ≥ ±1.96 for two tailed test at ∝= 0.05
The test statistic z is used
z= x`- μ/ σ/√n
Putting the values
Z= 8.02-7.18/1.952/√15
z= 0.84/0.51599
z= 1.6279
Since the calculated value of z= 1.6279 does not fall in the critical region Z ≥ ±1.96 we conclude that there is no difference between the population variance and the sample variance.
