Please show all work so it is easy for me to understand what steps were taken.

A polling group wishes to compare the point of view of Democrats and Republicans, ignoring those who do not express a party affiliation in terms of their positions regarding the siting of a medical marijuana dispensary. . Among the 290 self-declared Democrats, 195 indicate support having medical marijuana dispensaries in the city, compared to120 of the 190 self-declared Republicans. State and test the hypothesis of no difference in the proportion of Democrats and Republicans who support having marijuana dispensaries in Boston using the .05 level of significance. Make sure to interpret the findings (not just reject/retain null hypothesis).
