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
The whole number would be one and the remainder is 5. hope it helps.
Answer: umm wheres y at? after the Equal sign?
Step-by-step explanation:
Answer:
62
Step-by-step explanation:
Angle Formed by Two Chords
= 1/2(sum of Intercepted Arcs)
RST = 1/2 ( 47+77)
= 1/2 (124)
= 62
Interest paid after 30 years is $494,546.99.
Solution:
Principal (P) = $195,000
Interest rate (r) = 4.3%
Time (t) = 30 years
n = number of times interest calculated per year
n = 1
Compound interest formula:

where A is the final amount




A = 689546.99
Interest = Amount - Principal
= 689546.99 - 195000
= 494546.99
Interest paid after 30 years is $494,546.99.
