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
We know that
[volume of a <span>regular hexagonal prism]=[area of the base]*height
height=volume/area of the base
h=160/64-----> 2.5 m
[surface area </span><span>hexagonal prism]=2*[area of the base]+[perimeter of base]*h
</span>[surface area hexagonal prism]=2*[64]+[30]*2.5----> 203 m²
the answer is
203 m²
1. The total of x and 29.
This is because we see addition going on, so x+29 is the total of something
