Step-by-step explanation:
But 4+89=93.
Answer:
x = 12
Step-by-step explanation:
39/26 = 1.5
18/x = 1.5
18 = 1.5x
18/1.5 = x
12 = x
Looks like it is C.
Just put these numbers on a number line. Think money when you are working with negative numbers. if you owed two dollars to someone (-2 from your point of view), you would be much worse off than if you owed him - 0.75 dollars. 50 cents of debt is much better than 75 cents of debt. So - 0.5 is better than - 0.75.
The answer keeps on going like that ending in root(7).
D is in an order, but it is going the wrong way. It is going from largest to smallest.
The other 2 answers almost look random. A mixes plus and minus values. That does not suggest order. B has the 3 minus values all mixed up.
Answer:
There is not enough statistical evidence to state that the true proportion of grocery shoppers from Monday to Friday that goes most frequently on Fridays is different from 20%. The p - value is 0.0130.
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the population proportion.
Proportion in the null hypothesis (p0) = 0.2
Sample size (n) = 75
Sample proportion (sp) = 24/75 = 0.32
Significance level = 0.01
H0: p = 0.2
Ha: p
0.2
Test statistic = (sp - p0) / sqrt ((p0) (1-p0) / n)
Left critical Z value (for 0.01) = -2.5758
Right critical Z value (for 0.01) = 2.5758
Calculated statistic = (0.32 - 0.2) / sqrt ((0.32) (1-0.32) / 75) = 2.2278
Since, -2.5758 < Test statistic < 2.5758, the null hypothesis cannot be rejected. There is not enough statistical evidence to state that the true proportion of grocery shoppers from Monday to Friday that goes most frequently on Fridays is different from 20%. The p - value is 0.0130.
