Answer:
A or C
Step-by-step explanation:
Answer:
a. True
b. False
c. False
d. True
e. True
Step-by-step explanation:
a.
True,
A 99% confidence interval covers more than a 95% confidence interval.
This is because, more potential values must be allowed within the interval, to be more confident that the true population value falls within the interval
b.
False,
Decreasing the significance level will decrease the probability of making a type 1 error because the probability of a Type I error is the same as α.
c.
False,
The evidence is not sufficient to make a conclusion that µ = 5.
d. True
The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta).
The probability of not making this error is 1 - β
1 - β + β = 1
e.
True,
Large sample sizes can decrease the margin of error.
Because the relationship between margin of error and sample size is simple is that when the sample size increases, the margin of error decreases and vice versa
Answer:
124 ft2
Step-by-step explanation:
The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.
