a. Given : Sample size : n= 1078
The number of adults said it was a good thing= 659
Then , the proportion of success : 
b. The conditions to determine whether you can apply the CLT to find a confidence interval are :-
- The data must be randomly sampled.
- The sample size must be large (n>30).
- The sample values should be independent of each other.
Since the given data satisfies all the above conditions , so we can apply the CLT to find a confidence interval.
c. Given : Significance level : 
Critical value : 
The confidence interval for population proportion is given by :-
Hence, a 95% confidence interval for the proportion who believe immigration is a good thing is (0.582, 0.64).
There are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies.
4/25 prefered digital copies
21/25 prefered hard copies
21 is more than 4.
<span>The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the most likely to be true. </span>
Answer:
See below.
Step-by-step explanation:
<u>Part A:</u>
y = -3x + 2
y = -3x + 10
y = -3x
<u>Part B:</u>
y = 2x + 5
y = -3x + 5
y = -2x + 5
<u>Part C:</u>
y = -3x + 5
There can only be one line with this slope and intercept because the expression is very simple. There are only two pieces of information that define a straight line: slope and intercept. There is nothing else that can be altered to impact the line.
Answer:
Alternative A is the correct answer.
Step-by-step explanation:
For a function to have y-axis symmetry then it must be an even function such that; f(-x) = f(x). In alternative A, y = x^2 is an even function since; y(-x) = (-x)^2 = x^2 = y(x). The second function is also even since it has the absolute symbol. Finally, the cosine function is always an even function since cos(-x) = cos(x)
Answer:
$720
Step-by-step explanation:
12 * 30 = $360 per week
360 * 2 = $720 per 2 weeks
