Do colors affect mood? You are particularly interested to know which color gives peoplea sense of serenity and peacefulness. You conduct an experiment by making participantsstay for 20 minutes inside a room painted with a particular color (e.g., Red, Orange,Yellow, Green, Blue). With the use of temperature-sensitive cameras, you record theaverage body temperature of each individual during their stay inside each room (i.e.,lower body temperatures are associated with feelings of calmness and relaxation; higherbody temperatures - stimulation, excitement). Results are presented on the table.RedOrange39YellowGreenBlue4338333139433935344144423432423539373245403936354139383334 A. CONSIDER that the data is UNCORRELATED use alpha .05. Provide the following:1. Number of Participants2. Null Hypothesis3. ANOVA TABLE4. Cl of the F value5. Statistical Interpretation6. If the F is significant, perform a POST HOC test (pairwise comparison) usingthe TUKEY METHODNote: Present the computation of the q values. If the q value is significantwrite an asterisk after the q value, if insignificant write NS.7. Present your clusters and interpretation.

In West Texas, water is extremely important. The following data represent pH levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 is acidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable. (A) Look at a stem-and-leaf plot of the data. Use five lines per stem so that leaf values 0 and 1 str on one line, 2 and 3 are on the next line, 4 and 5 are on the next, 6 and 7 are on the next, and 8 and 9 are on the last line of he stem. Are there any unusually high or low pH levels in this sample of wells? a. there are no large gaps on either side of the plot, indicating that there are no outliers. there are no unusually high or low ph levels in the sample. b. there is a large gap beside some outliers on the right side of the plot. there are unusually high pH levels in the sample. c. there is a large gap beside…
Juvenile ground squirrels respond to predators by making “alarm calls” that can alert others to danger. A biologist conducted a study to investigate how squirrels respond to these alarm calls: run to burrow or freeze. The biologist played recordings of alarm calls for three samples of ground squirrels, grouped by age, and observed the squirrels’ responses. The data for the three age levels are shown in the table. Run to Burrow Freeze Total 1 to 5 Days Old 21 18 39 6 to 15 Days Old 16 24 40 16 to 25 Days Old 12 7 19 Total 49 49 98 If ground squirrels at different ages respond to the alarm signals in the same proportions, what would be the expected count for 6- to 15-day-old squirrels that freeze?

A special education teacher wants to test the effects of online learning. A class of ten children are given traditional instruction for the first month of class. The amount of student-teacher interaction was assessed—i.e., the average number of seconds it took for the student to respond when called upon. Beginning the second month, laptop computers are provided to each student. The data below show the averages for each student. Did it take significantly longer for the students to respond when using the laptop. Test the research using a two-tailed test and α = .05. Child no.. Traditional.

A researcher was interested in the effect of outdoor activity on mood. She hypothesized that spending time doing outdoor activity like walking in the forest would increase mood. She recruited 10 participants in her study. She had each participant walk a 2 km trail in the forest. Before and after the walk she had them rate their mood on a 5-pt Likert scale from 1 - very bad mood to 5 - very good mood. The data are reported in the table below. Mood Before Mood After 4 3 1 4 1 4 4 14 4 Copy or type the data into an Excel spreadsheet. Run the appropriate test to test the hypothesis at the 5% significance level (a = 0.05). On the excel spreadsheet, type your Step 5 answer including the numerical answer in formal APA format notation and the conclusion written in a sentence.
A glass manufacturing company wanted to investigate the effect of breakoff pressure and stopper height on the percentage of breaking off chips. The results are in the accompanying table. Complete parts (a) through (e). a. At the 0.01 level of significance is there an interaction between the breakoff pressure and the stopper height? b. is there an effect due to the breakoff pressure? c. is there an effect due to the stopper height? d. Plot the percentage breakoff for each breakoff pressure for each stopper height. e. Discuss the results of (a) through (d).

Ride services are on the rise, such as Uber and Lyft. You wondered if the recent news reports of crime occurring with these ride services impacted the usage of them, especially with women. You decide to conduct a survey about ride service usage among male and female college students. The results showed that 19 males use ride services and 11 do not. While 12 females use ride services and 18 do not. Calculate the degrees of freedom:
In a study assessing helping behavior among college students on their way to class, you recruit 10 students. You tell some participants that they are late for class and need to rush. You tell others they are right on time. Finally, you tell others they have lots of time before class. As they walk across campus, they come across a man (actually a confederate) who appears to need help. You measure the extent to which the participant noticed that the confederate needed help (1 = did not notice to 9 = really noticed). What is the acceptable level of risk? P >.05 p <.05 P = .05 P <.1
