Answer:
16
Step-by-step explanation:
Boys is written first so 3:4 the 3 stands for boy.
12 boys in class means that the 3 from 3:4 was multiplied 4 times so you do the same to other side. 4 times 4 is 16, therefore the answer is 16.
Considering the situation described, the hypothesis tested are given as follows:
- The null hypothesis is
- The alternative hypothesis is
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:
At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

Answer:0.6
Step-by-step explanation:
We can grab 2 points in this table and plug this into the slope formula: (y2-y1)/(x1-x2). The 2 easiest points would be (0,0) and (2, 1.2). Doing this would get us (1.2-0)/(2-0). Simplifying this would get us 1.2/2, or .6.
