Answer:
a) Null hypothesis:
Alternative hypothesis:
b)
The degrees of freedom are given by:
The p value for this case taking in count the alternative hypothesis would be:
Step-by-step explanation:
Information given
represent the sample mean for the amount spent each shopper
represent the sample standard deviation
sample size
represent the value to verify
t would represent the statistic
represent the p value f
Part a
We want to verify if the shoppers participating in the loyalty program spent more on average than typical shoppers, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case would be given by:
(1)
Replacing the info given we got:
The degrees of freedom are given by:
The p value for this case taking in count the alternative hypothesis would be:
Answer:
55 degrees
Step-by-step explanation:
A complementary angle equals 90 degrees so you know that the two angles together must equal that. The easiest way to set up these problems are to turn it into an algebraic equation. You know that angle a is 20 more than angle b, or angle a is (x+20) and angle b is (x). Your equation would read: x+x+20=90. Simply solve this equation then plug in the answer to whichever angle you need. 2x+20=90, 2x=70, x=35. Angle A is 20 degrees longer making it equal 55.
If the left-handed side column of the table is the values of y and the other column is x,
y= 0.7142857143x
Whereas,If the left-handed side column of the table is the values of x and the other column is y,
y=1.4x
