Use SPSS or Excel, print Output... 2. A toy manufacturer is testing 3 versions of a toy that is under development. Among other things, the manufacturer would like to see which version of the toy attracts the most attention. A psychologist allows a child to play with all 3 toys and records the amount of time (in minutes) spent playing with each. A sample of n = 5 children is used. Use the following data to determine whether there is a significant preference among the three toys. Use the .05 level of significance. (14 points) Toy Child | 1 2 3 A | 0 2 4 B | 2 2 8 C | 3 1 5 D | 0 3 6 E | 0 2 7 a. Step 1: State the hypotheses and set alpha level (2 points). b. Step 3: Calculate the value of the appropriate statistic. Using the SPSS or Excel print out, complete the table below (each bank is 2 points for a total of 6 points). Source SS df MS Sig Between Treatments F = Error c. Step 4: State your conclusion (3 points). Include in the conclusion the values that were compared (p-value or critical value to support your conclusion). In other words, include Step 2 of hypothesis testing (critical region) to support your conclusion. d. If there is a significant difference, conduct the Tukey’s HSD test. (3 points).

Solution

H0: the average time spent by each child is same

H1: the average time spent by each child is different

excel is used for the analysis.

Since p<0.05, we accept H0. Hence tukey\'s test is not required.
