Where is the question and what is it?
Answer:
if it is an a or b B is the best answer but if it a true of false. the answer is true
Step-by-step explanation:
Answer:
a) Null and alternative hypothesis:
b) A Type I error is made when a true null hypothesis is rejected. In this case, it would mean a conclusion that the proportion is significantly bigger than 10%, when in fact it is not.
c) The consequences would be that they would be more optimistic than they should about the result of the investment, expecting a proportion of students that is bigger than the true population proportion.
d) A Type II error is made when a false null hypothesis is failed to be rejected. This would mean that, although the proportion is significantly bigger than 10%, there is no enough evidence and it is concluded erroneously that the proportion is not significantly bigger than 10%
e) The consequences would be that the investment may not be made, even when the results would have been more positive than expected from the conclusion of the hypothesis test.
Step-by-step explanation:
a) The hypothesis should be carried to test if the proportion of students that would eat there at least once a week is significantly higher than 10%.
Then, the alternative or spectulative hypothesis will state this claim: that the population proportion is significantly bigger than 10%.
On the contrary, the null hypothesis will state that this proportion is not significantly higher than 10%.
This can be written as:
Answer:
-4.84
Step-by-step explanation:
the -4.84 is closest to the positive side of a number line. meaning -4.84 is greater
From the given problem statement alone, we can say that
the equation relating the area of the lawn mowed and the earnings has a linear
relationship. That is because there is a constant increase in the earnings per
area which is $1 per 1000 square feet.
Therefore the equation must be in the form of:
y = m x + b
where,
y = is the total earnings
m = is the fee per area = 1 / 1000
x = is the area of the lawn
b = is the fixed fee = 30
Therefore the equation becomes:
y = 0.001 x + 30
Rewriting this in terms for x since we are to find the
area:
x = (y – 30) 1000
when y = 204
x = (204 – 30) 1000 = 174,000 square feet
when y = 344
x = (344 – 30) 1000 = 314,000 square feet
when y = 450
x = (450 – 30) 1000 = 420,000 square feet
when y = 482
x = (482 – 30) 1000 = 452,000 square feet
when y = 504
x = (504 – 30) 1000 = 474,000 square feet
