1 (a-c)
You ask your graduate student to roll a die 5000 times and record the results.
a) Give the expected mean and standard deviation of the outcome.
b) The die roll experiment is repeated (though with a different graduate student – for some reason your previous student went to work with a different advisor). However in this case, the die is weighted so that a 6 shows up 11% of the time, a 1 shows up 25% of the time, and all remaining numbers show up 16% (each). Now what is the expected mean and sd of 5000 rolls?
c) What would happen if we changed the experiment to 10,000 rolls?

The effects of three concentrations of the ripening hormone (ethylene) were tested on tomato yield and quality. Five tomato cultivars (Shady Lady, Merced, Santa, Chiquita, and Celebrity) were grown in 5 replications in the field. The hormone was applied 4 weeks after flowering. Fruits were harvested 4, 5 and 6 weeks after the hormone application. Number of fruits per plot was counted, and fruits of each plot were classified to three groups of red, yellow-red and yellow. Fruit yield (kg/plot) and sugar concentration were measured. Fruit texture and taste were surveyed in a population of 50 people. For the survey, a sample of the fruits from each plot was given to people to eat and score taste from 1 to 10, and fruit texture from 1-5.

Dr. Schwartz wanted to examine the hypothesis that smelling peppermint affects exercise intensity, so she used random assignment in her first experiment on this topic. The peppermint group exercised in a room in which a peppermint scent was released once each minute, while the no peppermint group exercised in an unscented room. She measured the distance participants cycled in 20 minutes on indoor bicycles. After she completed that first experiment, Dr. Schwartz realized that perhaps her results in the first experiment could be attributable to the failure of random assignment to balance the weight of participants in the two groups. Thinking that this alternative explanation might explain why she got nonsignificant results in the first experiment, she decided to match participants on weight. She randomly assigned the two heaviest participants to either the peppermint or no peppermint conditions by flipping a coin, and then randomly assigned the next two heaviest participants, and so on.
Using the data shown below, conduct the appropriate statistical test in SPSS to determine whether there is a statistically significant difference between how far the participants in the peppermint condition rode vs. how far participants in the no peppermint condition rode.
