Answer:
a)
b) ![p_v =2*P(z](https://tex.z-dn.net/?f=p_v%20%3D2%2AP%28z%3C-1.53%29%3D0.126)
c) Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance
Step-by-step explanation:
Information given
represent the mean for 1
represent the mean for 2
represent the population standard deviation for 1
represent the population standard deviation for 2
sample size for the group 1
sample size for the group 2
z would represent the statistic
Hypothesis to test
We want to check if the two means for this case are equal or not, the system of hypothesis would be:
H0:![\mu_{1}=\mu_{2}](https://tex.z-dn.net/?f=%5Cmu_%7B1%7D%3D%5Cmu_%7B2%7D)
H1:![\mu_{1} \neq \mu_{2}](https://tex.z-dn.net/?f=%5Cmu_%7B1%7D%20%5Cneq%20%5Cmu_%7B2%7D)
The statistic would be given by:
(1)
Part a
Replacing we got:
![z =\frac{104-106}{\sqrt{\frac{8.4^2}{80} +\frac{7.6^2}{70}}}= -1.53](https://tex.z-dn.net/?f=z%20%3D%5Cfrac%7B104-106%7D%7B%5Csqrt%7B%5Cfrac%7B8.4%5E2%7D%7B80%7D%20%2B%5Cfrac%7B7.6%5E2%7D%7B70%7D%7D%7D%3D%20-1.53)
Part b
The p value would be given by this probability:
![p_v =2*P(z](https://tex.z-dn.net/?f=p_v%20%3D2%2AP%28z%3C-1.53%29%3D0.126)
Part c
Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance
Consider the intergers as, x and x+1
x+(x+1)=31
2x+1=31
2x=30
x=15
So, (x+1)=(15+1)=16 would be larger number.
I would multiply 46x1x1,000 to get 46,000. the. i would multiply 1x2.2x1 to get 2.2. i would then divide 46,000/2.2 to get 20,909.0909
The right answer for the question that is being asked and shown above is that: "180 - line." Tanisha cut a triangle with angles of 62°, 30°, and 88° in three pieces so that each piece had one angle of the triangle.She arranged the three angles <span>connected together such that the three corners of the triangle were all touching.</span><span> </span>
Try this solution:
for the circle A: circumference=6π, area=9π
for the circle B: circumference=12π, area=36π
PS. formula for circumference is 'L=2πr', for area is 'S=πr²'.
