Answer:
0.000005178
Step-by-step explanation:
we test for the goodness of fit
h0; drink preferences not changed
h1: drink preferences changed
alpha = 0.05
we solve for the test statistics
the chsquare test was performed in the attachment
Chi square = (O-E)²/E
chisquare = 32.30188
degree of freedom = n -1 = 6-1 = 5
using the chi distribution function on excel i calculated the p value
CHIDIST(32.30188, 5) =
P-value = 0.000005178
pvalue is less than 0.05 so we reject null hypothesis and conclude that there is sufficient evidence that drink preferences are changed.
the chisquare calculation is in the attachment. Thank you!
Answer:
Surface area: 592
Volume: 960
Step-by-step explanation:
First the surface area:
The formula for a rectangular prism is length times width, plus width times height, plus length times height times two
So,
lw= 12 times 10 = 120
wh= 10 times 8 = 80
lh = 12 times 8 = 96
(120 plus 80 plus 96) times 2 = 296 times 2 = 592
Surface area = 592
Second, volume:
Formula is length times width times height
12 times 10 times 8 = 120 times 8 = 960
Volume = 960 cubic cm.
Hope this helped. Sorry if I was wrong.
