Answer:

Step-by-step explanation:

Let the subscripts n and d represent day and night shifts respectively.

The null hypothesis is

H0 : μn = μd, μn - μd = 0

The alternative hypothesis is

H1 : μn > μd, μn - μd > 0

A) it is a one-tailed and also a right tailed test because of the greater than symbol in the alternative hypothesis.

B)The decision rule is to reject H0: μd ≥ μn If 0.10 > p value

C) Since the population standard deviations are known, we would use the formula to determine the test statistic(z score)

z = (xn - xd)/√σn²/nn + σd²/nd

Where

xn and xd represents sample means for night and day respectively.

σn and σd represents population standard deviations for night and day respectively.

nn and nd represents number of samples

From the information given,

xn = 341

xd = 336

σn = 25

σd = 19

nn = 61

nd = 56

z = (341 - 336)/√25²/61 + 19²/56

z = 1.22

Test statistic = 1.22

D) From the normal distribution table, the probability value corresponding to the area above the z score is 1 - 0.8888 = 0.1112

Since the level of significance, 0.02 < 0.1112, do not reject H0.

Solve h^2− 42 = −h using the quadratic formula.

aleksandr82 [10.1K]

Hi there! The answer is C. h = 6 or h = −7

${h}^{2} - 42 = - h$
Add h to both sides of the equation.

$h {}^{2} + h - 42 = 0$
First we need to find the discriminant (which can be found using the formula D = b^2 - 4ac)

$d = 1 {}^{2} - 4 \times 1 \times - 42 \\ d = 1 + 168 \\ d = 169$

Now we can plug in our found values into the quadratic formula.

$x = \frac{ - b - \sqrt{d} }{2a} \: \\ or \\ \: x = \frac{ - b + \sqrt{d} }{2a}$

Plug in.
$x = \frac{ - 1 - \sqrt{196} }{2 \times 1} = \frac{ - 1 - 13}{2} = \frac{ - 14}{2} = - 7 \\ or \\ x = \frac{ - 1 + \sqrt{196} }{2 \times 1} = \frac{ - 1 + 13}{2} = \frac{ 12}{2} = 6$

Hence, the answer is C. h = 6 or h = −7
