Answer:
Input value/x = 9
Step-by-step explanation:
The output value means y and the input value means x.
So they've told us the output value y = 4.5
Sub this into the function they gave us to get x
y=x/2
4.5=x/2
9=x
Answer:1/6
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
7/10 8/11 please tell me if this is helpful, I know 7/10 is right but idk about 8/11
