Answer:
the y-intercept is (0,5)
Step-by-step explanation:
Answer:
For this case we can find the critical value with the significance level and if we find in the right tail of the z distribution we got:
The statistic is given by:
(1)
Replacing we got:
Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of households with one person is significantly higher than 0.27
Step-by-step explanation:
We have the following dataset given:
represent the households consisted of one person
represent the sample size
estimated proportion of households consisted of one person
We want to test the following hypothesis:
Null hypothesis:
Alternative hypothesis:
And for this case we can find the critical value with the significance level and if we find in the right tail of the z distribution we got:
The statistic is given by:
(1)
Replacing we got:
Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of households with one person is significantly higher than 0.27
Answer:
Martin is wrong because in the Graph we can clearly see that the graph will be translated left 3 unit from the parent graph. The vertex point will be (-3,0)
Step-by-step explanation:
2580/3 * 100 = 860 * 100 = 86,000
Check:
86,000 * 0.03(3%) = 2580
The selling price of the house is $86,000.
The height is 52 feet.
Using t=3, we have:
-3² + 15(3) + 16 = -9 + 45 + 16 = 52
