200×39.37=7874
the answer is 7874 in
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.
A line graph, or line chart, shows info as a series of data points that are connected by line segments.
Given:
The matrix multiplication
To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is 
and the order of second matrix is 
, then the order of these two matrices is 
.
We have,
Here, the order of first matrix is 
and the order of the second matrix is 
. So, the order of the second matrix is 
. It is also written are 2 by 1.
Therefore, the correct option is A.
