Answer:
The group's claim is not supported at 1% significance level.
Step-by-step explanation:
given that a local group claims that the police issue more than 60 speeding tickets a day in thire area
The data they collected for 2 weeks is given below:
70 48 41 68 69 55 70
57 60 83 32 60 72 58
![\bar x = 60.2\\s = 12.9\\n=14](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%2060.2%5C%5Cs%20%3D%2012.9%5C%5Cn%3D14)
Std error of mean = ![\frac{12.9}{\sqrt{14} } \\=3.4477](https://tex.z-dn.net/?f=%5Cfrac%7B12.9%7D%7B%5Csqrt%7B14%7D%20%7D%20%5C%5C%3D3.4477)
![H_0: \bar x=60\\H_a: \bar x >60](https://tex.z-dn.net/?f=H_0%3A%20%5Cbar%20x%3D60%5C%5CH_a%3A%20%5Cbar%20x%20%3E60)
(Right tailed test at 1% significance level)
Mean difference = 0.10
Test statistic t with df 13 = mean difference/std error
= 0.029
p value = 0.4886
Since p >0.01, we accept null hypothesis
The group's claim is not supported at 1% significance level.
Answer:N/B The amount is in thousands
The total amount earned by a Bachelor's person be $x:
amount earned by a masters person will be $(2x-38)
Total amount earned by the two individuals will be:
x+(2x-38)=115
solving for x we get:
x+2x-38=115
3x=115+38
3x=153
x=153/3
x=51
also:
2x-38=2*51-38=64
therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.
