Answer:
There was no error
Step-by-step explanation:
There are two types of statistical errors, the type 1 error and the type 2 error. In this case we refute the null hypothesis when the hypothesis is, in fact, false, because the mean process is 9 days instead of 7. Therefore we made no errors.
If the null hypothesis were True, a type 1 error would have ocurred. If the null hypothesis were false and we didnt refute it, then a type 2 error would have ocurred.
Answer: The correct answer is A) 0.98 feet
Step-by-step explanation: I took the test and got it correct.
I think the correct answer from the choices listed above is option D. The equation that would satisfy all of the points plotted above would be y=-2x. From the plot, we can see that the y-intercept is equal to zero and by using two points we can calculate the slope to be equal to -2. Giving an equation which is y=-2x.
Answer:
c
Step-by-step explanation:
they are supposed to match
Answer: a) 300000 b) 200 c) 20000
Step-by-step explanation:
Round so that there is only 1 sig. fig. in the answer
a) 300000 (rounded up to 300,000 not 280,000 as there would be 2 sig figs, 2 and 8)
b) 200 (rounded down)
c) 20000 (rounded up to 20,000 not 18,000 as there would be 2 sig figs, 1 and 8)
The trailing zeroes do not count as sig. figs. so the above answers all have only one sig. fig.
