To see if her hope is correct, she surveys 36 recently married couples and finds that the average cost of weddings in the sample was $27,338. Assuming that the population standard deviation is $4532, is there sufficient evidence to support the bride's hope at the 0.02 level of significance? Step 3 of 3: Draw a conclusion and interpret the decision. Answer 3 Points Keypad Keyboard Shortcuts We fall to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the bride's hope that the mean cost of a wedding is less than $29.205. We reject the null hypothesis and conclude that there is sufficient evidence at a 0.02 level of significance to support the bride's hope that the mean cost of a wedding is less than $29,205.
