Answer:
Type I error.
Step-by-step explanation:
The decision to shut the process is triggered by the conclusion that the average height is significantly different from 66 mm.
This means that the null hypothesis, that states that the average height is not significantly different from 66 mm (μ=66), has been rejected.
If the null hypothesis is rejected, the error that can have been made is to reject a true null hypothesis, when the process is functioning to specification and the average length is not significantly different from 66.
This is a Type I error, that happens when a true null hypothesis is rejected.
Answer:
He used about 15 gallons
Step-by-step explanation: if he drove 617.3 miles and he gets 41 miles per gallon, then we can use the formula 41x=617.3 to solve this formula, we would divide 617.3 by 41 to isolate x. 617.3 divided by 41 is equal to 15 and therefore x = 15
Answer:
I think they are asking the area of the triangle so we are going with that.
Step-by-step explanation:
Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.
so it is 4 cm wide
and 8 cm tall
length x width = area
8 x 4 = 32
32/2 = 16
So your answer should be 16 cm
