The proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents.
(a) Conduct a hypothesis test to determine if these data provide strong evidence the rate of sleep deprivation is different for the two states.
(b) It is possible the conclusion of the test in part (a) is incorrect. If this is the case, what type of error was made?
Step-by-step explanation:
We start by stating the null hypothesis
H0: p1 = p2
No difference is existent
H1: p2 not equal to p2
There is a difference
We find the z statistic using microsoft excel or using the formula in the attachment
= -1.68
From the normal table, p value = 0.099
The p value is greater than 0.05 so we fail to reject the null hypothesis and conclude there is no difference
B. If answer in part a is incorrect then we have made a type ii error. A type 2 error occurs when we accept a false null hypothesis.

Step-by-step explanation:
x^2 + 6x + 10 cannot be factored
x^2 + 3x -4 = (x-1)(x+4)
x^2 - 3x -4 = (x+1)(x-4)
x^2 + 6x +5 = (x+1)(x+5)
Answer: x² + 6x + 10
Step-by-step explanation:
The four can be factored by the set of real numbers, except the first one.
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
- x² - 3x - 4 can be factor as (x - 4)(x + 1)
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
And the first one, the number is 10, the factos of 10 is 1,2,5,10, none of the factors would apply the situation 6x.

45 × 1 = 45

Jillian is an analyst for a ride sharing app that connects users with drivers. She wonders if drivers in Dallas are more or less likely to cancel rides than drivers in Houston. She takes a random sample of 1000 rides from Dallas and finds that 30 were cancelled. A random sample of 1000 rides from Houston shows 24 cancelled rides. She used these results to test H: Pp = PH versus H, :pp + PH. The test statistic was z = 0.83 and the P-value was approximately 0.41. Assume that all conditions for inference were met. At the a = 0.01 level of significance, is there sufficient evidence to conclude that the proportion of cancelled rides is different between the two cities?
A Yes, since the P-value is greater than 0.01.
B Yes, since the test statistic is greater than 0.01.
C No, since the P-value is greater than 0.01
D No, since the test statistic is greater than 0.01.
Answer:
C No, since the P-value is greater than 0.01
Step-by-step explanation:
Since in the given situation we assume that all the conditions are ,met
And, at the a = 0.01 significance level we that that the proportion of the cancelled rides between the two cities would not sufficient as the P value is more than 0.001
Therefore the correct option is c.

If the line x = 3 is the axis of symmetry of a parabola, which coordinates below could be x-intercepts of the parabola?
0 (-8.0) and (-2,0)
0 (-1,0) and (5,0)
0 (-1,0) and (7,0)
O (-3,0) and (3, 0)
Answer:
(-1,0) and (5,0)
Step-by-step explanation:
The coordinates of the parabola are (-1,0) and (7,0).
The correct option is C.
What is a parabola?Parabola is a curve drawn in a plane. Where any point is at an equal distance from a fixed point (the focus ) and a fixed straight line (the directrix ).
Given:
The line x = 3 is an axis of symmetry of a parabola.
That means the coordinate of the x-intercept is (3, 0)
From the given choices;
(A). (-8.0) and (-2,0)
The coordinate of the x-intercept = (-8-2/2, 0) = (-5, 0)
(B). (-1,0) and (5,0)
The coordinate of the x-intercept = (-1+ 5/2, 0) = (2, 0)
(C). (-1,0) and (7,0)
The coordinate of the x-intercept = (-1 + 7/2, 0) = (3, 0)
(D) (-3,0) and (3, 0)
The coordinate of the x-intercept = (-3 + 3/2, 0) = (0, 0)
Therefore, the coordinates are (-1,0) and (7,0).

SOMEONE PLEASE ANSWER AND EXPLAIN I’LL MARK BRAINLIEST THANK YOU
Answer:
20 visits.
Step-by-step explanation:
Fitness Universe has a 1 time payment of $50, and each visit will cost $5.50
Non-members pay $8 per visit. Let each visit be signified by the variable, v. Set the equation:
5.50v + 50 = 8v
Isolate the variable, v. Note the equal sign, what you do to one side, you do to the other. Subtract 5.50v from both sides:
5.50v (-5.50v) + 50 = 8v (-5.50v)
50 = 8v - 5.50v
50 = 2.50v
Isolate the variable, v. Divide 2.50 from both sides:
(50)/2.50 = (2.50v)/2.50
v = 50/2.50
v = 20

Answer:
160 meters
Step-by-step explanation:
Before I begin, note that distance = rate * time (or d = r * t)
To solve this problem, we need to find what point these two people have the same distance. (so Janiyah covers the same distance as Connor)
So, let's set the time that Janiyah takes as x (in seconds). So, he covers
d = r * t, or 8x meters
Then, Connor's equation would be
d = r * t
d = 5x + 60 (because he got a 60 meter headstart)
Because d is the same in both equations, to solve for the amount of time they run:
8x = 5x + 60
Subtract 5x from both sides.
3x = 60
x = 20
Then, to find Janiyah's distance (you can also use Connors because the two distances are equal), put x = 20 into 8x
8x = 8 * 20 = 160
So, Janiyah ran 160 meters.
Just in case, let's check if this is correct. Connor's distance equals Janiyah's, so
5x + 60 = 160
5 * 20 + 60 = 160
100 + 60 = 160
160 = 160
True.
So, the answers are correct.
