2. Based on a poll of registered voters in a large city, 120 out of a random sample of 250 women intended to vote for Donald Trump in the 2020 presidential election and 132 out of a random sample of 240 men intended to vote for Donald Trump. A. Is there convincing evidence that there is a difference in the proportion of all women and the proportion of all men in this city who intended to vote for Trump in the 2020 presidential election at the a = 0.05 level? B. Based on your conclusion, what type of error could you have just made? Describe a consequence of making this type of error.

Step 1
P-value of Z-statistics for two tailed is 0.1212
Since the p-value is greater than 0.05 level of significance, the
result is not significant at P<.05
Hence we fails to reject the null hypothesis and conclude that there is no difference in the proportion who intended to vote for Trump among male and female PM=PF
