Chelsea Hutto and ‘decaffeinated drink’. Different participants took part in each condition.

Looking at the group means in the table below, which of the following statements best describes the data?(1 pt)Decaffeinated DrinkCaffeinated DrinkNo Email12.0819.83Email11.985.49a.A significant interaction effect is likely to be present between caffeine consumption and email access.b.There is likely to be a significant main effect of caffeine.c.The effect of email is relatively unaffected by whether the drink was caffeinated.d.The effect of caffeine is about the same regardless of whether the person had email access.31. What type of ANOVA is used when there are two independent variables each with more than two levels, and with different participants taking part in each condition? (1 pt)32. An experiment was done to look at whether there is an effect of the number of hours
spent practicing a musical instrument and gender on the level of musical ability. A sampleof 30 (15 men and 15 women) participants who had never learnt to play a musical instrument before were recruited. Participants were randomly allocated to one of three groups that varied in the number of hours they would spend practising every day for 1 year (0 hours, 1 hours, 2 hours). Men and women were divided equally across groups. Allparticipants had a one-hour lesson each week over the course of the year, after which their level of musical skill was measured on a 10-point scale ranging from 0 to 10. An ANOVA was conducted on the data from the experiment. Looking at the output below, which of the following sentences is correct? (1 pt)
Chelsea Hutto = 33. In a replication of the above experiment, slightly different results were obtained, and the
following graph illustrates these new findings. Which of the following sentences best describes the pattern of results shown in the graph? (1 pt)
