Answer:
A. We have extremely strong evidence to reject H0.
Step-by-step explanation:
Let P be the proportion of non-retirees in 2015 who did not think that Social Security would be able to pay a retirement benefit by the time that they retire.
According to the data null and alternative hypotheses should be:
: P=0.60
: P<0.60
Test statistics is -4.29 and p-value of the statistics is p<0.001
At every significance levels higher than 0.001, we can reject the null hypothesis since p<0.001.
The answer is 15
From the graph:
Car A traveled 60 miles in one hour
Car B traveled 75 miles in one hour.
Car B travels 15 more miles per hour
notice in the chart, the big yellow and the big orange, 23% and 29%, which make up 23+29 = 52%, more than 50%.
and the ages range is 18-25 and 26-34, namely 18 - 34.
X=7 All you need to do is combine like terms and then move the appropriate terms to the appropriate side.
