The answer is in my photos.
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: The expenses of the fundraiser is $1500
Step-by-step explanation:
P(n) models the fundraiser's profit (in dollars) where n represents the number of tickets that are sold. The equation is expressed as
P(n) = 70n - 1500
A negative profit means the expenses exceeded the income from tickets. Looking at the model, for the charity organization to make profits, the product of the number of tickets sold and the cost per ticket must exceed $1500. If it is below $1500, then it is a negative profit. This means that the expenses is $1500
