Hypothesis testing of shares

Reference no: EM13113835

Last year, television station WXYZ's share of the 10 P.M. news audience was approximately equal to, but not greater than, 25%. The station's management believes (and would like to claim for advertising purposes) that the current share is higher than last year's 25% share. In an attempt to substantiate this claim, the station surveyed a random sample of 400 news viewers and found that 146 watched WXYZ news. At the .01 level of significance, do you believe the station's claim to be correct?
