yes
Step-by-step explanation:
if the cross-products are equal then the two fractions form a proportion:
is 4(12) = 3(16) ?
yes, 48=48
He used 11 quarts out or 3 gallons .
I know because in 1 <span>gallon</span> there are 4 quarts .
You do 4*3 =12.
Than you -1 from 12 and get 11.

Answer:
0.0445937
Step-by-step explanation:
-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.
-Assuming normal distribution, the test statistic is calculated as:
![z=\frac{Sample \ statistic-Null \ statistic}{\sigma/\sqrt{n}}\\\\=\frac{406-411}{\sqrt{225/26}}\\\\=-1.6997](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BSample%20%5C%20statistic-Null%20%5C%20statistic%7D%7B%5Csigma%2F%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B406-411%7D%7B%5Csqrt%7B225%2F26%7D%7D%5C%5C%5C%5C%3D-1.6997)
-we then find the p-value of the test statistic from the z-tables:
P-value=0.0445937
