The statistical software output for 90% confidence interval is:
Two sample proportion confidence interval:
p1 : proportion of successes for population 1
p2 : proportion of successes for population 2
p1 - p2 : Difference in proportions
Note: the standard error is calculated using separate estimates for the proportions
90% confidence interval results:
Hence,
The 90% confidence interval is 0.304 to 0.333
No, It is not plausible that there is no difference.
