Answer:
There is no sufficient evidence to reject the company's claim at the significance level of 0.05
Step-by-step explanation:
Let
be the true mean weight per apple the company ship. We want to test the next hypothesis
vs
(two-tailed test).
Because we have a large sample of size n = 49 apples randomly selected from a shipment, the test statistic is given by
which is normally distributed. The observed value is
. The rejection region for
is given by RR = {z| z < -1.96 or z > 1.96} where the area below -1.96 and under the standard normal density is 0.025; and the area above 1.96 and under the standard normal density is 0.025 as well. Because the observed value 1.4583 does not fall inside the rejection region RR, we fail to reject the null hypothesis.
Answer:
3/4
Step-by-step explanation:
Parallel lines have same slopes.
Answer:
.
Step-by-step explanation:
Start by finding the slope of this line.
If a slanting line goes through
and
, where
, the slope of this line would be:
.
The line in this question goes through
and
. Hence, the slope of this line would be:
.
If a slanting line with a slope of
and goes through the point
, the equation of this line in the point-slope form would be:
.
For the line in this question, the slope is
. Take
as the chosen point on this line. The point-slope form equation of this line would be:
.
Rewrite to obtain the equation of this line in the slope-intercept form:
.
