The construction for the two sided and one sided hypothesis
is the same so the answer is letter d. the explanation behind this is: If you
use a two-tailed test it just means that you need to allot half of your alpha
to testing statistical significance. If your alpha is equal to 0.05, then this
means that 0.025 must be in each tail of the distribution while for the one-tailed
test, you will only allot your alpha in one-side.
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.

Step-by-step explanation: 1.1 x
Answer:
- 10
Step-by-step explanation:
Step 1:
5 ( x - 4 ) = 7x Equation
Step 2:
5x - 20 = 7x Multiply
Step 3:
- 20 = 2x Subtract
Step 4:
x = - 20 ÷ 2 Divide
Answer:
x = - 10

Answer:
Largest Median: Same
Largest Range: Castro
Largest IQR: Castro
Step-by-step explanation:
With a box-and-whisker plot, the box represents the upper and lower quartiles, the vertical line inside the box represents the median, and the lines on either side of the box show the high and low of the range.
Largest Median: Medians are the same because the verticle line inside the boxes is at 7 for both
Largest Range: Ms Castro's Class- the lines on either side of the box for Ms Castro go from 1-10 while the other class only goes from 4-10.
Largest IQR (interquartile range) Ms. Castro's class: their IQR goes from 5-8 while the other class only goes from 6-8
