Let's assume that a greedy feature selection strategy for feature selection is applied based on Pearson correlation. Put the following actions in the correct order (use 1 for the first action, and 4 for the last action): Compute Pearson correlation between each feature and the target Select the best number of features Sort features based on absolute correlation score Train your model applying a repeated validation strategy, where on each iteration a different number of features is used

A medical researcher is working on a new treatment for a certain type of cancer. Theaverage survival time after diagnosis on the standard treatment is two years. In an earlytrial, she tries the new treatment on three subjects who have an average survival timeafter diagnosis of six years. Although the survival time has tripled, the results are notstatistically significant even at the 0.10 significance level. The explanation isA) the placebo effect is present, which limits statistical significance.B) the sample size is small.C) that although the survival time has doubled, in reality the actual increase is reallytwo years.D) the calculation was in error. The researchers forgot to include the sample size.
Suppose that a health researcher is interested in determining whether the distance between the patient’s residence and source of care, and # of disability days significantly predict the number of visits at a local hospital.

Does stress affect the recall ability of police witnesses? This issue was studied in an experiment that tested eyewitness memory a week after a nonstressful interrogation of a cooperative suspect and a stressful interrogation [the way of questioning] of an uncooperative suspect. The numbers of details recalled a week after the incident are summarized in the margin (based on data from "Eyewitness Memory of Police Trainees for Realistic Role Plays," by Yuille et al., Journal of Applied Psychology, Vol. 79, No. 6). Use 0.01 level of significance to test the daim in the artidle that stress decreased the amount recalled. Assume equal population variances. Nonstress Stress n = 40 X= 53.3 n2 = 40 = 45.3 S, = 13,2 S = 11.6 a. Claim (in symbolic form): Ho: На: b. level of significance: test-statistic: tail of distribution: c.

The authors of the paper "Age and Violent Content Labels Make Video Games Forbidden Fruits for Youth"† carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young game players. Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read the description with an age restrictive label of 7+, indicating that the game was not appropriate for children under the age of 7. Others read the same description, but with an age restrictive label of 12+, 16+, or 18+. The paper gave data for 12- to 13-year-old girls. Data consistent with summary values in the paper are shown below. 7+ label 12+ label 16+ label 18+ label 5 4 6 8 9 5 4 6 6 5 8 6 5 6 6 7 5 3 10 7 6 5 9 4 4 3 6 10 5 8 6 6 10 5 8 8 5 9 5 7 Do the data provide convincing evidence that the mean rating associated with the game…
7/8) individuals tend to vary in their taste sensitivity. Is it possible that this trait may be linked to a person’s genetics? A scientist identified the genotype of 30 individuals for a gene she believes to be responsible for taste sensitivity. She compares taste sensitivity across the homozygous dominant, heterozygous, and homozygous recessive individuals. Q) What is the explanatory variable here? Q) What kind of variable is the subject’s genotype?
A new process for producing a type of novolac resin is supposed to have a mean cycle time of 3.5 hours per batch. Seven batches are produced, and their cycle times, in hours, were3.45, 3.47, 3.57, 3.42, 3.40, 3.53, 3.59Can you conclude that the mean cycle time is less than 3.5 hours? Test at a 10% significance level and report a p-value.
6) In a study of proctored and nonproctored tests in an online Intermediate Algebra course,researchers obtained the data for test results given below (based on “Analysis of Proctoredversus Non-proctored Tests in Online Algebra Courses,” by Flesch and Ostler, MathAMATYCEducator, Vol. 2, No. 1). Use a 0.01 significance level to test the claim that students takingnonproctored tests get a higher mean than those taking proctored tests.Group 1 (Proctored): ? = 30, ?̅= 74.30, ? = 12.87Group 2 (Nonproctored): ? = 32, ?̅= 88.62, ? = 22.09
