Step-by-step explanation:

Sample size = n =2500

Sample persons favouring =1900

Population proportion = 78%

Population std deviation =

(Two tailed test)

Sample proportion =

p difference = -0.02

Test statsitic z = p diff / std dev of p

=

Since this lies outside 95% of (-1.96, 1.96) we reject H0.

The provided data reveals that the proportion of  all citizens are in favor of increasing the tax on cigarette cannot be taken as 78%.
