Last year television station wxyzs share of the 10 p.m., Ask an Expert

Statistics

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?
