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
The integer of 3 is negative (-3). Glad to help
Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)
Step-by-step explanation:
Self explanatory question, you set a quadratic equation to zero
For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0
Then, you would factor, that equals to (x – 8)( x + 2) = 0
(X-8)=0 (X+2)=0
X+2=0
-2 =-2
X=-2
X-8=0
+8 =+8
X=-8
To check you would simply plug in the values into the quadratic equation. They would both equal 16=16
:) Multiple choices are difficult but the best answers are C or D GO WITH YOUR GUT!
Answer b is correct have a great day :) it has very special value
