A wedding website states that the average cost of a wedding in 2017 was $25,764. One concerned bride hopes that the average is less than reported. To see if her hope is correct, she surveys 55 recently married couples and finds that the average cost of wedding in the sample was $23,015. Assuming that the population standard deviation is $7235, is there sufficient evidence to support the bride's hope at the 0.1 level of significance?
