<h3>The projected amount the average American spent on health care in 2014 is $ 10075.91</h3>
<em><u>Solution:</u></em>
Given that,
The average American spent $8,508 on health care in 2011
The cost of health care is projected to rise about 5.8% per year for the years 2012-2022
<em><u>The increasing function is given as:</u></em>
Where,
y is future value
a is initial value
r is growth rate in decimal
t is number of years
From given,
a = 8508
t = 2011 to 2014 = 3 years
<em><u>Substituting the values, we get,</u></em>
Thus the projected amount the average American spent on health care in 2014 is $ 10075.91
Answer:
(a) Fail to reject because the P-value is greater than alpha.
(b) The percentage of adults that would erase all of their personal information online if they could is less than or equal to 52%.
Step-by-step explanation:
We are given that assume a significance level of alpha equals 0.05 and use the given information to complete parts;
Original claim : More than 52% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.2504.
<u><em>Let p = % of adults who would erase all of their personal information online if they could</em></u>
So, Null Hypothesis, : p
52% {means that percentage of adults that would erase all of their personal information online if they could is less than or equal to 52%}
Alternate Hypothesis, : p > 52% {means that percentage of adults that would erase all of their personal information online if they could is more than 52%}
<u><em /></u>
(a)The conclusion about the null hypothesis is that;
We fail to reject null hypothesis, because the P-value is greater than alpha as 0.2504 > 0.05.
(b) The correct conclusion based on the fact that null hypothesis has been rejected is;
The percentage of adults that would erase all of their personal information online if they could is less than or equal to 52%.
