Half of the people were told that they would ndividual meal costs and the other half were told to split the cost equally among the six people at the table. The data in SplitBill each person ordered (in Israeli shekels) and the payment method (Individual or Split). Use StatKey or other technology to mn distribution using these data to test whether there is sufficient evidence to conclude that the mean cost is lower when diners an when they split the bill equally. bution contains a proportion of about 95% between nt evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. bution contains a proportion of about 95% between nt evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. bution contains a proportion of about 95% between Cient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. bution contains a proportion of about 90% between nt evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally.

Split the Bill? Exercise 2.153 on page 105 describes a study to compare the cost of restaurant meals when people pay individually versus splitting the bill as a group. In the experiment 48 subjects were randomly assigned to eight groups of six diners each. Half of the people were told that they would each be responsible for individual meal costs and the other half were told to split the cost equally among the six people at the table. The data in SplitBill includes the cost of what each person ordered (in Israeli shekels) and the payment method (Individual or Split). Use StatKey or other technology to construct a randomization distribution using these data to test whether there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. Randomization distribution contains a proportion of about 95% between -8.5 to +8.6 Yes, there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. Randomization distribution contains a proportion of about 95% between -14.5 to +14.6 Yes, there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. Randomization distribution contains a proportion of about 95% between -8.5 to +8.6 No, there is not sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. Randomization distribution contains a proportion of about 90% between -8.5 to +8.6 Yes, there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally.
