Psychologists Erik Erikson suggested that individuals go through eight developmental stages of life. Erikson believed that at stage 8 (age 65 to death), an adult's fear of death can be predicted by thesatisfaction they feel when reflecting back on their lives. To investigate, a psychiatrist interviewed a random sample of adults age 65 and older, and scored them on their satisfaction with their lives andtheir fear of death. The psychiatrist wants to confirm Erikson's theory. What can be concluded with a =0.01?fear of deathsatisfied43422103247348.4a) Select and compute the appropriate statistic.---Select---b) Input the appropriate value(s) to make a decision about Ho.p-valueX ; Decision: Fail to reject H0 vc) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).If not appropriate, input and/or select "na" below..Effect Size = 0.266; Magnitude: nad) Make an interpretation based on the results.More life satisfaction significantly predicts more fear of death.More life satisfaction significantly predicts less fear of death.Life satisfaction does not significantly predict fear of death.

Suppose you want to estimate the percentage of videos on YouTube that are cat videos. It is impossible for you to watch all videos on YouTube so you use a random video picker to select 1000 videos for you. You find that 2% of these videos are cat videos. A. What is the sample? B. Label each of the following as an observational unit, a variable, a statistic, or a parameter i. Percentage of all videos on YouTube that are cat videos. ii. 2% iii. A video in your sample. iv. The proportion of videos in your sample that are cat videos.
In the following situation we want to compare the mean responses in several populations.Are you a morning person, an evening person, or neither? Does this personality trait affect how well you perform? A sample of 111 students took a psychological test that found 17 morning people, 35 evening people, and 59 who were neither. All the students then took a test of their ability to memorize at 8 a.m. and again at 9 p.m. You analyze the score at 8 a.m. minus the score at 9 p.m. Give the degrees of freedom of the ANOVA F test. numerator df = denominator df =
In this chapter we leaned that a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. Therefore, which of the following z-score values represents the location farthest from the mean? O +1.00 O -2.00 O -1.00 O +0.50

A recent study has shown that approximately 31.6% of Canadians are considered 'supertasters,' or people who experience the sense of taste with greater intensity than average. Consider a sample of 23 Canadians, each of whom are asked to indicate if they are a supertaster or not. Please use this information to answer the following questions.a. How many of the Canadians sampled can we expect to be supertasters?Answer:_______people. Round to at least FOUR digits after the decimal if necessary. b. What is the standard deviation of the number of people sampled who are supertasters?Answer:______people. Round to at least FOUR digits after the decimal if necessary.
