(A) Explanation Given: The value of a = − 2.1 and b = − 4 for the equation d = a + b sin 4 θ . Calculation: Consider the equation d = a + b sin 4 θ with a = − 2.1 and b = − 4 . Thus, the equation becomes d = − 2.1 − 4 sin 4 θ . Substitute the value of θ = 30 ° and obtain the value of d as follows. d = − 2.1 − 4 sin 4 ( 30 ° ) = − 2.1 − 4 sin ( 120 ° ) = − 2 (B) To determine To find: The difference d in degrees between the estimated and the actual horizontals when θ = 10 ° .

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

"Coffee drinkers often claim that the caffeine in the coffee makes them more alert. A researcher wonders if this enhanced alertness is merely an illusion or if caffeine actually makes people more alert. To test the effect of caffeine on alertness, the researcher asks people to drink one cup of caffeinated coffee, one cup of plain water, one cup of caffeinated water, or one cup of decaffeinated coffee. After drinking the beverage each participant was given an electroencephalogram (EEG). The researcher hypothesized that the caffeinated beverages would result in greater electrical activity than the non-caffeinated beverages. Which of the following would be most likely to increase the size of the treatment effect in this study? " Only use people in the study who are between the ages of 25 and 35 rather than 25 and 75. Increase the amount of beverage participants drink from one cup to two cups. Have experienced EEG technicians collect data rather than train students…

Gender and Direction. In the paper “The Relation of Sex and Sense of Direction to Spatial Orientation in an Unfamiliar Environment” (Journal of Environmental Psychology, Vol. 20, pp. 17–28), J. Sholl et al. published the results of examining the sense of direction of 30 male and 30 female students. After being taken to an unfamiliar wooded park, the students were given some spatial orientation tests, including pointing to south, which tested their absolute frame of reference. The students pointed by moving a pointer attached to a 360◦ protractor. The absolute pointing errors, in degrees, are provided on the WeissStats site. a. Use the Mann–Whitney test to decide whether, on average, males have a better sense of direction and, in particular, a better frame of reference than females. Perform the test with α = 0.01. b. Obtain boxplots and normal probability plots for both samples. c. You used the pooled t-test to conduct the hypothesis test. Based on your graphs in part (b), which test is…

To point south, the students moved a pointer attached to a 360◦ protractor. The absolute pointing errors, in degrees, for students who rated themselves with a good sense of direction (GSOD) and those who rated themselves with a poor sense of direction (PSOD) are provided on the WeissStats site. Can you reasonably apply the two-standard-deviations F-test to compare the variation in pointing errors between people who rate themselves with a good sense of direction and those who rate themselves with a poor…
