For the volume of a rectangular prism (box-shape), all we have to do is multiply, length * width * height.
We know from the text that the hole the construction company will be digging is 12 yards long, 7 yards wide, and 3 yards deep, so all we need to do to find the volume of the dirt removed in cubic yards is multiply, 12 * 7 * 3.

12 * 7 = 84

84 * 3 = 252

The construction company will have removed 252 cubic yards of dirt for the swimming pool.
Hope that helped! =)

The test statistic of zequals1.18 is obtained when testing the claim that pgreater than0.2. a. Identify the hypothesis test as b
labwork [276]

Answer:

a) Right Tailed

b) p-value = 0.119

c) We fail to reject the Null Hypothesis(H_{o})

Step-by-step explanation:

We have the following data:

Test Statistic = z = 1.18

Claim: p > 0.2

Part a) Type of Test

Remember that when there is Greater than, Lesser than or any synonymous word in the claim, this means that the test is one-tailed.

  • Greater than word indicates a Right Tailed Test
  • Lesser than word indicates a Left Tailed Test

Since, the claim is that p is greater than 0.2, the hypothesis test will be Right Tailed.

Part b) P-value

We have to find the p-value for the given test statistic. Since, the test statistic is a z-value we will use z-table to find the p-value for this score. Since, this z-score is for claim that p is greater than 0.2, so we will find the p-value(probability) of score being above 1.18

The p-value of z being greater than 1.18 comes out to be 0.119. i.e.

p-value = 0.119

Part c) Decision

Calculated p-value is 0.119 and significance level = 0.05. The rule is:

  • If p value is equal to or lesser than the significance level, then we reject the null hypothesis
  • If p value is greater than the significance level, then we fail to reject the null hypothesis

Since, in this case our p-value is greater than the significance level, we fail to reject the null hypothesis (H_{o}).

1. At a certain company, the human resources department surveyed employee satisfaction. They collected the following data.
Setler79 [48]
Question (a)
The relationship between satisfaction score and salary is a positive one. The graph shows a positive correlation. It means, the higher the salary, the higher the satisfaction score

Question (b)
We will substitute the value of x=65000 into the equation y=0.0005x+60 = 0.0005(65000)+60=92.5

Question (c)
The constant 0.0005 is the increase of satisfactory score by 0.0005 for every pound increase in the salary

Find an equation of the line parallel to y-3x +4 that passes through (2,3)
My name is Ann [436]

Answer:

y = 3x - 3

Step-by-step explanation:

y = 3x + 4

If two lines are parallel, their slopes are equal

so slope will be 3

given m = 3, y = 3, x = 2

y = mx + b

3 = 3(2) + b

3 = 6 + b

b = -3

so y = 3x - 3
