Question

A radio show producer believes that a new proposed format would be preferred by only 25% of their current listeners. A survey of 100 current listeners showed that 17 favored the new format. Find the test statistic z and test the claim. H0:p= 0.25. use the significance level a=.05.

A hypothesis test is to be performed for a population proportion. For the given sample data and null hypothesis, compute
the value of the test statistic, z =
Λ
P-PO
√ Po (1- Po)/n
