Answer:
The third options
Step-by-step explanation:
Counting we can see that 10 students went to two or less states, and 10 went to three or more
Answer:
y = 2x+3
Step-by-step explanation:
y = mx + b
This is the slope intercept form of the equation of a line where m is the slope and b is the y intercept
We are given a slope of 2 and a y intercept of 3
Substituting these values into the equation
y = 2x+3
Answer:
a. Type I error (rejecting a null hypothesis when it is true).
b. Correct conclusion (reject a null hypothesis when it is false).
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>Now suppose that the results of carrying out the hypothesis test lead to rejection of the null hypothesis.</em>
<em>Classify that conclusion by error type or as a correct decision if in fact:</em>
<em>a. the mean post-work heart rate of casting workers equals the normal resting heart rate of 72 bpm. </em>
<em>b. exceeds the normal resting heart rate of 72 bpm.</em>
In case a, the conclusion is wrong and we have rejected a null hypothesis that is true. This is a Type I error, and it has a probability equal to the level of significance α.
In case b, the conclusion is correct, as the mean post-work heart rate indeed exceeds the normal resting heart rate of 72 bpm.
The answer is multiplying the height by the length which would be 16
(q ° r) = -32
(r ° q) = 101
