15x-15 that is the answer to the question
Answer:
Step-by-step explanation:
Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).
Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)
Snorkel, mask, and flippers Slope intercept form: y = 2x + 10
Solution :
Population proportion, P = 77%
Sample size is given by n = 55
Sample proportion =
Null hypothesis
The population proportion of the fatalities of the drivers that are related to alcohol = 77%
%
Alternate hypothesis,
Therefore, the test statistics =
= -3.2
Critical value = -1.64
and the rejection zone : test zone, -1.645
Therefore, we fail rejecting
p value 0.0582
rejection zone :: p value , 0.01
So we fail to reject
Thus the data does not indicate the population proportion of the drivers fatalities which are related to the alcohols which is less than 77% in the county of Kit Carson.
