A research team investigates the potential association between hours of work and smoking. They want to see whether there is a di

fference in number of smokes per day between smokers who work about 40 hours per week and those who work 55 hours or more. If they were to use the hypothesis testing procedure for this research question, what would be the appropriate test statistic to use

Answer:

chi-square

Step-by-step explanation:

According to the given situation, Chi-square statistic would be considered for as we have to determine whether working hours and smoking are attached with each other or not.

To know whether working hours based on smoking or there is an important relationship between both- So Chi-square statistic would be used

Therefore the test that should be used is chi-square

Which transformation of Figure A results in Figure A' ?
MariettaO [177]

Option B: a counterclockwise rotation of 90° about the origin

Explanation:

From the graph, we can see the coordinates of the figure A are (0,2), (-1,6) and (-4,4)

The coordinates of the figure A' are (-2,0), (-6,-1) and (-4,-4)

<u>Option B: a counterclockwise rotation of 90° about the origin </u>

The transformation rule for a coordinate to reflect a counterclockwise rotation of 90° about the origin  is given by

(x,y)\implies (-y,x)

Let us substitute the coordinates of the figure A

Thus, we have,

(0,2)\implies(-2,0)

(-1,6)\implies (-6,-1)

(-4,4)\implies(-4,-4)

Thus, the resulting coordinates are equivalent to the coordinates of the figure A'.

Therefore, the figure is a counterclockwise rotation of 90° about the origin .

Hence, Option B is the correct answer.

The candy shop puts 10 ounces of gummy bears in each box. How many boxes do they need to fill if there are 2,114 pounds of gummy
Tems11 [23]

Answer:

Number of boxes= 3,382.4 = 3,383 boxes

Step-by-step explanation:

Giving the following information:

Number of ounces per box= 10 ounces

Total pounds= 2,114

We know that one pound is 16 ounces.

<u>To calculate the number of boxes, we need to use the following formula:</u>

Number of boxes= total ounces / ounces per box

Number of boxes= (2,114*16) / 10

Number of boxes= 3,382.4 boxes
