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.
V = 297 for a square pyramid, I hope its right..
Answer:
the answer is 144 feet
Step-by-step explanation:
to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12
to find the area of the square you do A= lw which in this case it would look something like this:
A= 12(12) you use 12 twice because square sides are always equal
then you multiply which gives you A= 144
