Answer:
There is no enough evidence that the proportions are different.
Step-by-step explanation:
We have to perform a hypothesis test on the difference of proportions.
In this case, the sample size is equal.
The null and alternative hypothesis are
The significance level is assumed to be 0.05.
The weighted average p, as the sample sizes are the same, is the average of both proportions:
The standard deviation is
The z-value for this sample is:
The P-value for z=-0.9375 is P=0.3485.
The P-value (0.35) is greater than the significance level (0.05), so the null hypothesis is failed to reject.
There is no enough evidence that the proportions are different.
