... This problem has been solved! See the answer In a​ study, researchers wanted to measure the effect of alcohol on the hippocampal​ region, the portion of the brain responsible for​ long-term memory​ storage, in adolescents. The researchers randomly selected 10 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm cubed. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x =8.08 cm cubed and s=0.7 cm cubed. Conduct the appropriate test at the 0.01 level of significance. State the null and alternative hypotheses. Upper H 0​: mu equals 9.02 Upper H 1​: mu less than 9.02 ​ Identify the​ t-statistic. ​(Round to two decimal places as​ needed.

Q.2. Because of potential variability in aging due to different castings and segments on the castings, a Latin square design with N=7 was used to investigate the effect of heat treatment on aging. With A= castings, B = Σχ = 297,216.90, segments, C = heat treatments, summary statistics include x... = 3815.8, Σχ = 297,155.01, and 297,200.64, = 297,317.65. Obtain the ANOVA table and test at level .05 the hypothesis that heat treatment has no effect on aging.

Can people tell the difference between a female nose and a male nose? This research question was examined in an article. Eight Caucasian males and eight Caucasian females posed for nose photos. The article states that none of the volunteers wore nose studs or had prominent nasal hair. Each person placed a black Lycra tube over his or her head in such a way that only the nose protruded through a hole in the material. Photos were then taken from three different angles: front view, three-quarter view, and profile. These photos were shown to a sample of undergraduate students. Each student in the sample was shown one of the nose photos and asked whether it was a photo of a male or a female. The response was then classified as either correct or incorrect. The following table was constructed using summary values reported in the article. Sex ID View Front Profile Three-Quarter Correct 29 26 23 Incorrect 11 14 17   Is there evidence that the proportion of correct sex…

The radius of the spherical ball is 8 centimeters. She wraps the first cord around the hemisphere of the ball until it is completely covered, as shown in Figure 1. She cuts the cord and removes it from the ball. She then wraps the second cord around the bottom circle of the ball until it is completely covered, as shown in Figure 2. She again cuts the cord and removes it from the circular base. Which of the following correctly compares the lengths of the cords and best justifies the reason for this relationship? The length of the first cord must be approximately equal to the length of the second cord because the surface area of the hemisphere is the same as the area of its…

The Moon Illusion refers, roughly speaking, to the common experience that the moon appears larger (and closer to us) when it is near the horizon than when it is at its zenith. To investigate, we have designed an experiment in which participants must adjust the diameter of a variable circular light placed at eye level to match the diameter of a fixed circular light placed well above eye level. (See, for example, Kaufman, L. & Rock, I. (1989), "The moon illusion thirty years later," chapter 8 in M. Hershenson (Ed.) The Moon Illusion, Hillsdale, NJ: L. Earlbaum.) We have tested 25 participants and recorded for each participant her experimental "adjustable/ fixed ratio." Our data are summarized in the following histogram.

Researchers conducted a study to learn how early childhood education relates to a child's future earning potential. They gathered a random sample of 200 5-year-old children and divided them into two groups. Children who had preschool education were gathered into the first group. All other children were placed in the second group. By age 30, the subjects who received preschool education were 80% less likely to have received welfare in their 20s. Part A: This study was Select an answer Part B: Having a preschool education (yes or no) was one variable in this study. Which is it? Response Explanatory Part C: Receiving welfare in one's 20s (yes or no) was another variable in this study. Which is it?

Eapatel The Moon Illusion refers, roughly speaking, to the common experience that the moon appears larger (and closer to us) when it is near the horizon than when it is at its zenith. Wishing to investiçate the causes of the illusion (which are still debated), we have designed an experiment in which participants must adjust the diameter of a variable circular light placed at eye level to match the diameter of a fixed circular light placed well above eye level. (See, for example, Kaufman, L. & Rock, 1. (1989), The moon illusion thirty years later," chapter 8 in M. Hershenson (Ed.) The Moon Musion, Hillsdale, NJ: L. Earlbaum.)
