Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the distance in miles
y ----> the time in hours
we have
The distance is equal to subtract 35 miles from 230 miles
The time is equal to subtract 1:30 pm from 4:30 pm
substitute in the formula of speed
<em>Isolate 3 hours</em>
<em>Isolate 195 miles</em>
Answer:
Step-by-step explanation:
We are given the following in the question:
The needle size should not be too big and too small.
The diameter of the needle should be 1.65 mm.
We design the null and the alternate hypothesis
Sample size, n = 35
Sample mean, = 1.64 mm
Sample standard deviation, s = 0.07 mm
Type I error:
- It is the error of rejecting the null hypothesis when it is true.
- It is also known as false positive error.
- It is the rejecting of a true null hypothesis.
Thus, type I error in this study would mean we reject the null hypothesis that the average diameter is 1.65 mm but actually the average diameters of the needle is 1.65 mm.
Thus, average diameter is 1.65 mm and we decide that it is not 1.65 mm.
