Answer: No, It does not indicates that the population proportion of consumers loyal to Chevrolet is more than 47%.
Step-by-step explanation:
Let p denotes the proportion of consumers loyal to Chevrolet.
As per given , we have
Since the alternative hypothesis is right-tailed so the test would be a right-tailed test.
Also , it is given that ,Chevrolet did a study of a random sample of 1006 Chevrolet owners and found that 490 said they would buy another Chevrolet.
i.e. n = 1006
x= 490
Test statistic :
, where p=population proportion.
= sample proportion
n= sample size.
i.e.
P-value (for right-tailed test)= P(z>1.08)=1-P(z≤1.08) [∵P(Z>z)=1-P(Z≤z)]
=1- 0.8599=0.1401 [By z-value table.]
Decision : Since p-value (0.14) is greater than the significance level () , it means we are failed to reject the null hypothesis.
Conclusion : We have sufficient evidence to support the claim that about 47% of the general consumer population in the United States is loyal to the automobile manufacturer of their choice.
Hence, it does not indicates that the population proportion of consumers loyal to Chevrolet is more than 47%.
You need to understand Rise over Run (r/r) to find these equations.
Rise over run works by counting how far a point on the line is from another.
You do this by first counting how much higher or lower a point is from another then how far it is from the left or right side.
So to answer the equation for #2,
Your Rise over Run is: 3/4
Which translates to Y = 4x + 3
Finding line #1 is actually much easier. All you need to know is how far up it is, which is 8 units
So that’s just Y = 8
Finding a slope parcel to the 2nd line is a lot easier than you might think.
We know the slope of line #2 is Y = 4x + 3.
Parallel means if two lines were next to each other and kept going, they won’t intercept. Like the equals sign, =.
So to find a parallel line, you can just add or subtract the same number from Y to X
Y = 4x + 3
4x + 2 = 6x
3 + 2 = 5
=
Y = 6x + 5
Answer:
4
Step-by-step explanation:
44 yeah yeah what about the other
Hi There! The answer is 10 and 1. Because you add 10 and 1 to get 11 and 10 times 1 equals 10. Hope this helps.
First, we want to find the difference in monthly fee and per minute costs.
20 - 15 = 5
0.25 - 0.05 = 0.20
So basically we now know that we need to make up for 5 dollars of monthly cost difference, and for every minute we talk with the two plans at the same time, it's different by 0.20.
Now, we just can divide 5 dollars by the difference of 0.20, which you would get 25 minutes from.
So you would have to talk for 25 minutes for the two plans to be the same cost.
Assuming that you used them at the same time, not just used B or A.
