Answer:

Step-by-step explanation:

We are given an equation , so we first need to simplify the equation

lets distribute the x on parenthesis first

2x^2 -x- 15 = x^2 + x.

Now bring all terms to the left so we get

2x^2-x-15-x^2-x=x^2+x-x^2-x

x^2-2x-15=0

Now since all terms are in one side , so we now factor the equation

(x-5)(x+3)=0

Now apply the zero product property to get

x-5=0 or x+3=0

x=5 or x=-3

solution x=-3 or x=5

C

Answer:

(a) The null hypothesis will be rejected.

(b) Type I error

(c) The null hypothesis will not be rejected. The error is type II error.

Step-by-step explanation:

The hypothesis provided is:

H_{0}: \mu = 0\\ H_{a} : \mu > 0

The p-value of the test obtained is 0.03

(a)

Decision rule for hypothesis testing, based on p-value, states that if the p-value is less than the significance level (α) then the null hypothesis is rejected and vice versa.

The significance level is α = 0.10

Then,

p-value = 0.03 < \alpha  = 0.10

Thus, the null hypothesis will be rejected.

Conclusion:

The null hypothesis is rejected stating that the value of μ is more than 0.

(b)

If the decision in​ (a) is an​ error, i.e. the null hypothesis is rejected when in fact it is true, this type of error is known as type I error.

(c)

The significance level is α = 0.01

Then,

p-value = 0.03 > \alpha  = 0.01

Thus, the null hypothesis will not be rejected.

Conclusion:

The null hypothesis was not rejected stating that the value of μ is 0.

If this decision is an error, i.e. the null hypothesis was not rejected when in fact it is false, this type of error is known as type II error.
