Based on a random sample of 50, a 95% confidence interval for the population proportion was computed. holding everything else constant, which of the following will reduce the length of the confidence interval by half? (check all that apply): a. double the sample size. b. change the confidence level to 99.7%. c. decrease the sample proportion by half. d. quadruple the sample size. e. change the confidence level to 68%.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

may i see the picture? it would a lot, xox

c. side angle side. u shares the same sides
