Answer:
1/4
Step-by-step explanation:
So the slope of a line is the change in y over the change in x. So that would be 4/16 or 1/4
Answer:
B. 0.4542 to 0.5105
Step-by-step explanation:
A 90% confidence interval for p is calculated as:
This apply if n*p≥5 and n*(1-p)≥5
Where p is the proportion of sample, n is the size of the sample and is equal to 1.645 for a 90% confidence.
Then, in this case p, n*p and n*(1-p) are calculated as:
n*p = (850)(0.4824) = 410
n*(1-p) = (850)(1-0.4824) = 440
So, replacing values we get:
It means that a 90% confidence interval for p is 0.4542 to 0.5105
