A large nationwide company with 1200 employees claims that the number of days missed by its employees due to illness is below the national average of 7. A random sample of 40 employees resulted in a mean of 6.6 days with a standard deviation of 1.8. The hypothesis test resulted in a p-value of 0.084. Which of the following statements is true?
A. There is a 10% chance that the null hypothesis is true and a 8.3% chance that the alternative hypothesis is true.
B. There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.
C. Since the probability that the mean number of days is below 7 is small, the null hypothesis is likely true.
D. If the mean number of days missed the company is 7 the probability of obtaining a sample mean of 66 days or lower is 0.063.

Answers

Answer 1

The last part of the question before the options is meant to be;

The hypothesis test using α = 0.1 resulted in a p-value of 0.084. Which of the following statements is true?

Answer:

B: There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.

Step-by-step explanation:

Significance value is α = 0.1

p-value = 0.084

Now, we want to test the claims that the number of days missed by its employees due to illness is below the national average of 7.

Now the p-value is basically a probability.

Thus, p = 0.084 can be written as 8.4%

It seems this 8.4 is an approximate version of 8.3 because the options use 8.3%.

Thus, Option B is the closest answer.

0-4-9 = -13 or -4-9 = -13

Explanation:

Basically it starts at 0, then it moves to the left of the number line meaning it subtracts. It moves to the left by 4, so it is subtracting 4 from 0. Then it moves to the left again by 9, so you subtract 9 from 0-4

In the end, it is 0-4-9 or you can remove the 0 and be -4-9

Step-by-step explanation:

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

[tex]f\left(x\right)\:=x^3+2x^2-16x-32[/tex]

Let us determine the factors by solving

[tex]\:\left0\right\:=x^3+2x^2-16x-32\:[/tex]

[tex]\left(x+2\right)\left(x+4\right)\left(x-4\right)=0[/tex]

Using the zero factor principle:

if  [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

[tex]x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0[/tex]

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

(x+2)(x+4)(x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

(x-2)(x+6)

jordan can jog 1/3 of a mile in 1/6 of an hour.what is his speed in miles per hour

Answers

Answer:

The answer is  2 miles per hour

Step-by-step explanation:

Given

distance = 1/3 miles

time taken = 1/6 hour

Required,

The speed with which Jorgan Jogs

Step two:

We know that the formula for the situation is

Speed= distance/time

Speed= 1/3/1/6

Speed= 1/3*6/1

multiply the numerator by the inverse of the denominator

Speed=6/3

Speed= 2 miles per hour

A plane takes off from an airport on the bearing S 29°W. It continues for 20 minutes then changes to bearing S 52°W and flies for 2 hours 20 minutes on this course then lands at a second airport. If the plane's speed is 420 mph, how far from the first airport is the second airport? Round to the nearest mile.
A. 1011 mi
B. 1111 mi
C. 1010 mi
D. 1110 mi

Answers

Answer: 1110 miles

Step-by-step explanation:

Given that :

Speed (V) = 420 mph

t1 = 20 minutes = 20/60 = 0.3333 hour

t2 = 2 hours 20 minutes = 2.333 hours

Distance = speed * time

d1 = 420 * 0.333 = 140 miles

d2 = 420 * 2.33333 = 979.98 = 980 miles

Using cosine rule :

x = sqrt(d1² + d2² - 2(d1 * d2) cos 157

x = sqrt(140^2 + 980^2 - 2(140 * 980) cos157

x = sqrt(1232586.5)

x = 1110.2191

x = 1110 miles

If the probability is 0.65 that a marriage will end in divorce within 20 years, what is the probability that out of 7 couples just married in the next 20 years
(A) None will be divorced?
(B) All will be divorced?
(C) Exactly 6 will be divorced?
(D) At least 6 will be divorced?

Answers

Answer:

0.00064

0.049

0.185

0.234

Step-by-step explanation:

Using binomial distribution formula :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

p = 0.65

1 - p = 1 - 0.65 = 0.35

n = 7

(A) None will be divorced?

P(x = 0) : 7C0 * 0.65^0 * 0.35^7

= 1 * 1 * 0.00064339296875

= 0.00064

(B) All will be divorced?

P(x = 7) : 7C7 * 0.65^7 * 0.35^0

1 * 0.04902227890625 * 1

= 0.049

(C) Exactly 6 will be divorced?

P(x = 6) : 7C6 * 0.65^6 * 0.35^1

7 * 0.075418890625 * 0.35

= 0.18477628203125

= 0.185

(D) At least 6 will be divorced?

P(x ≥ 6) = p(6) + p(7)

P(6) = 0.185

P(7) = 0.049

P(x ≥ 6) = 0.185 + 0.049 = 0.234
