Question

Construct and interpret a 90% confidence interval estimate for the difference between the proportion of technology crowd-funding projects and film and video crowd-funding projects that are successful.

The researchers performing this study can be [enter percentage] confident that the difference in the population proportion of successful technology crowd-funding projects and successful film and video crowd-funding projects is

[contained in, less than lower bound, greater than upper bound, equal to midpoint] the interval from [   ] to [ ].

alpha = .1

Zstat = -1.35

p-value = .177

P1 = 132/363 and P2 = 353/872

I think the answer is 90%, contained in, and I got -.0714 to -.0110 .
