Answer:
A.)
H0: μ ≤ 31
H1: μ > 31
B.)
H0: μ ≥ 16
H1: μ < 16
C.)
Right tailed test
D.)
If Pvalue is less than or equal to α ; we reject the Null
Step-by-step explanation:
The significance level , α = 0.01
The Pvalue = 0.0264
The decision region :
Reject the null if :
Pvalue < α
0.0264 > 0.01
Since Pvalue is greater than α ; then, we fail to reject the Null ;
Then there is no significant evidence that the mean graduate age is more Than 31.
B.)
H0: μ ≥ 16
H1: μ < 16
Null Fluid contains 16
Alternative hypothesis, fluid contains less than 16
One sample t - test
C.)
Null hypothesis :
H0 : μ ≤ 12
. The direction of the sign in the alternative hypothesis signifies the type of test or tht opposite direction of the sign in the null hypothesis.
Hence, this is a right tailed test ; Alternative hypothesis, H1 : μ > 12
d.)
If Pvalue is less than or equal to α ; we reject the Null.
Answer:
$2.35 for one video
Step-by-step explanation:
You set up two equations:
$7.50= p + 2v
$12.20= p + 4v
You then set both equal to p
p=-4v+12.20 and p=-2v+7.50
So you can set them equal to each other and solve for v (the cost of one video)
v= $2.35
You would need 18 3/4 quarts of sparkling water.
Answer: The sides are increase by a factor of 3 and the angles remain the same.
When you are performing a dilation, you multiply the coordinates by 3. This will increase the length of all the sides by a factor of 3. However, the measures of the angles will remain the same. We call these similar figures.
