Researchers investigated how the size of a bowl affects how much ice cream people tend to scoop for themselves. People were randomly given either a 17 oz or a 34 oz bowl, and were invited to scoop as much ice cream as they liked. Did the bowl size change the selected portion size? The summaries are shown to the right. Test an appropriate hypothesis and state your conclusions. (Assume a significance level of 0.10.) Small Bowl 30 4.89 oz Large Bowl 30 6,42 oz y y 1,89 oz 3.05 oz Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: HL- Hs =0 O B. Ho: HL-Hs #0 HA: HL-Hs >0 HA: HL-Hs =0 OC. Ho: HL-Hs = 0 O D. Ho: HL-Hs =0 HA: HL-Hs <0 HA: HL -Hs #0
