11w times 6x

240w times 18y

you always use the last numbers and that would equal...

____________________________________________________________

66x times 4320y=

285120 divide it by 6= 47520

then by 12

47520 divided by 12=

3960-80= 3880

3880 divided by 16 times 4

your answer is 970y

Svetlanka [38]

Answer:

z=3.8196

Step-by-step explanation:

-We notice that this is a normal distribution problem.

-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:

$z=\frac{x-\mu_o}{\sigma/\sqrt{n}}\\\\=\frac{8745-8500}{1200\sqrt{350}}\\\\\\=3.8196$

Hence, the test statitic is z=3.8196
