Investigation Results – Using the given data, investigate the possible relationships between Life Expectancy as the response variable (y) and each of the three explanatory variables (x). For each x variable, you will complete the following steps. (Note: you will do parts a – d three times!) Construct a scatter diagram displaying the relationship between x and y. You can use graph paper and draw the diagram by hand, use your calculator and take a picture of the screen, or use the online site: https://www.desmos.com/, which will allow you to print or save your diagram. Calculate and state the sample correlation coefficient r. Describe the type of correlation, if any, and interpret the correlation in the context o-f the data. Determine if the correlation is significant. Use α = 0.05 and show all steps of this process.

LDL - low density lipoprotien - cholesterol is considered the bad cholesterol. A pharmaceutical company conducts a clinical trial on people with high levels of LDL cholesterol. The trial involves a random sample of n = 16 persons who have high levels of LDL. Each person has their LDL level measured prior to the beginning of the drug trial. Each person is then to take a new drug that is believed to lower ones LDL levels. After a period of 4-weeks, the LDL level of each person is measured again. The difference between the initial LDL level and the LDL-level four weeks after taking the drug is then computed. -0.56, -0.07,-0.2, -0.42, -0.32, -0.99, -0.26, -0.32, -0.73, -0.51, -0.59, -0.62, -0.78, -0.04, -0.5, 0.13 Data from the sample, are saved in the Download.csv file. Assuming the difference in the LDL-levels is Normally distributed, find a 97% confidence interval for μ, the mean difference in the LDL-level of a person after taking the drug for four weeks. Use at least four decimals for…

Allergic reactions to poison ivy can be miserable. Plant oils cause the reaction. Researchers at Allergy Institute did a study to determine the effects of washing the oil off within 5 minutes of exposure. A random sample of 1000 people with known allergies to poison ivy participated in the study. Oil from the poison ivy plant was rubbed on a patch of skin. For 500 of the subjects, it was washed off within 5 minutes. For the other 500 subjects, the oil was washed off after 5 minutes. The results are summarized in the following table. Let's use the following notation for the various events: W = washing oil off within 5 minutes, A = washing oil off after 5 minutes, N = no reaction, M = mild reaction, S = strong reaction. Find the following probabilities for a person selected at random from this sample of 1000 subjects. (Use 3 decimal places.) (a) P(N) P(M) P(S) (b) P(N | W) P(S | W) (c) P(N | A) P(S | A) (d) P(N and W) P(M…

Self-Esteem Scores In a study of a group of women science majors who remained in their profession and a group who left their profession within a few months of graduation, the researchers collected the data shown here on a self-esteem questionnaire. At a = 0.05, can it be concluded that there is a difference in the self-esteem scores of the two groups? Use the P-value method. Leavers X₁ = 3.05 Stayers X2 = 2.96 σ₁ = 0.75 02 = 0.75 n = 103 n2 = 225
A researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the alternative hypothesis (H1) put forth about the treatment? Group of answer choices The treatment has no effect on anxiety. The treatment adds a constant to each anxiety score. The treatment multiplies each anxiety score by a constant. The treatment has an effect on anxiety.
De SFU The analgesic effects of music are well known, but most of the studies have been done with adults and most of the music has been classical. You want to know whether children who choose their own music or audiobook to listen to after a surgery experience less pain and whether that depends on a severity of a surgery. To answer this question, you asked children who underwent minor and major surgeries to listen to music or a story of their choice, or to sit with noise-cancelling headphones for 30 minutes and then to point to a pain face that best illustrated their level of pain.
