Answer:
The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions

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
