In the sample, p̂ = 158/300 = 0.527. The resulting P-value is 0.18. What is the correct interpretation of this Pvalue?

a. Only 18% of the city residents support the tax increase.

b. There is an 18% chance that the majority of residents supports the tax increase.

c. Assuming that 50% of residents support the tax increase, there is an 18% probability that the sample proportion would be 0.527 or greater by chance alone.

d. Assuming that more than 50% of residents support the tax increase, there is an 18% probability that the sample proportion would be 0.527 or greater by chance alone.

e. Assuming that 50% of residents support the tax increase, there is an 18% chance that the null hypothesis is true by chance alone.

Members of the city council want to know if a majority of city residents supports a 1% increase in the sales tax to fund road repairs. To investigate, they survey a random sample of 300 city residents and use the results to test the following hypotheses:

H₀: p=0.50
H_a: p>0.50

where p is the proportion of all city residents who support a 1% increase in the sales tax to fund road repairs.
