Answer:

Type I error: Reject <em>H₀</em>: <em>p</em> = 0.02 when in fact <em>p</em> = 0.02.

Type II error: Fail to Reject <em>H₀</em>: <em>p</em> = 0.02 when in fact <em>p</em> ≠ 0.02.

Step-by-step explanation:

The complete question is:

Write a sentence describing the type I and type II errors for the hypothesis test for the indicated claim.

"A hospital spokesperson states that 2% of emergency rooms visits by college undergraduates are for alcohol related health problems."

Solution:

A type I error occurs when we discard a true null hypothesis (<em>H₀</em>) and a type II error is made when we fail to discard a false null hypothesis (<em>H₀</em>).

The claim made by the hospital spokesperson is, 2% of emergency rooms visits by college undergraduates are for alcohol related health problems.

The hypothesis can be defined as:

<em>H₀</em>: The proportion of emergency rooms visits by college undergraduates for alcohol related health problems is 2%, i.e. <em>p</em> = 0.02.

<em>Hₐ</em>: The proportion of emergency rooms visits by college undergraduates for alcohol related health problems is not 2%, i.e. <em>p</em> ≠ 0.02.

A type I error will be committed when we conclude that the null hypothesis can be rejected, i.e. proportion of emergency rooms visits by college undergraduates for alcohol related health problems is not 2%, when in fact we are rejecting a true null hypothesis, i.e. the proportion is 2%.

A type II error will be committed when we conclude that the null hypothesis cannot be rejected, i.e. proportion of emergency rooms visits by college undergraduates for alcohol related health problems is 2%, when in fact we are failing to reject a true null hypothesis, i.e. the proportion is not 2%.

Solve the following equation. Then place the correct mixed number in the box provided. 5x/7=22
natka813 [3]
We have that
<span> 5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5

the answer is
x=30 4/5</span>

QUESTION 1 The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.Assume that the driving
GarryVolchara [31]

Answer:

P(X>300)

And we can find this probability with the complement rule:

P(X>300)= 1-P(X

Step-by-step explanation:

For this case we define the random variable X ="driving distance for the top 100 golfers on the PGA tour" and we know that:

X \sim Unif (a=284.7, b=310.6)

And for this case the probability density function is given by:

f(x) =\frac{1}{310.6 -284.7} =0.0386 , 284.7 \leq X \leq 310.6

And the cumulative distribution function is given by:

F(x) =\frac{x-284.7}{310.6-284.7} , 284.7 \leq X \leq 310.6

And we want to find this probability:

P(X>300)

And we can find this probability with the complement rule:

P(X>300)= 1-P(X
