To test whether memory changes with age, a researcher conducts an experiment in which there are four groups of six subjects each. The four groups are listed below. All subjects are in good health and matched in other important variables such as years of education, IQ, gender and motivation. Each subject is shown a series of nonsense syllables (a meaningless combination of three letters such as DAF or FUM) at a rate of one syllable every 4 seconds. The series is shown twice after which the subjects are asked to write down as many of the syllables as they can remember. The number of syllables remembered by each subject is shown below.

30 Years Old 40 Years Old 50 Years Old 60 Years Old
14 12 17 13
13 15 14 10
15 16 14 7
17 11 9 8
12 12 13 6
10 18 15 9

Please use SPSS to compute the test statistic for the following problems. For those questions, please turn in the appropriate SPSS output.

  1. Perform the appropriate analysis
  2. Wherever appropriate, calculate and report effect size(s)
  3. Make a decision regarding the null hypothesis and write an APA-style conclusion interpreting your statistical results with regard to the aims of the experiment and as you would write it up in a report, including the statistical evidence to back it up.

Describe the changes in color and state of matter that occurred when the iodine is heated.

Compare the color of crystals on the evaporating dish bottom with those in the iodine reagent bottle.

Compare the colors of the two cyclohexane solutions after the samples were added.

What is the identity of the deposited substance on the bottom of the evaporating dish? Explain your reasoning.

What pieces of evidence demonstrated that physical changes occurred? Explain your reasoning in a logical, scientific manner based on the experimental evidence.

Compare the original copper metal with the material obtained after heating the copper.

Compare the color of the liquid obtained after putting the unheated copper in the sulfuric acid to the color of the liquid obtained after putting the heated copper (black material) in the sulfuric acid. In other words, compare the color of the liquids in the two test tubes.

Do copper and the black material (copper(II) oxide) have the same physical and chemical properties? Explain your reasoning.

A researcher is interested in whether there are changes in child aggression after they watch another child get something that they want. She devises an experiment where children come into her lab and are given worn and broken toys to play with. After a short time, a new child is brought into the room and is given new, shiny toys to play with. The researcher wants to know whether there are changes in aggressive behavior among the children with the broken, worn toys after they see the new children playing with new, shiny toys. She measures the number of aggressive behaviors displayed by the children who were given the worn and broken toys both before and after they watch the new children playing with new, shiny toys. Her findings are summarized in the table below.

Child Before After
A 16 18
B 10 11
C 17 19
D 4 6

A national chain of coffee shops claimed that 60% their servers are notified of changes in their work schedules in advance. A random sample of 200 servers showed that 100 were notified of changes in their schedule in advance. Perform a hypothesis test at 95% confidence to determine if the claim could be true. To get full credit state your null and alternate hypothesis, show test statistic and p-value and state your conclusion: could the company’s claim be true? YES or NO
