Question

Suppose you computed r=−0.142 using a sample size of 22 data points. Using the critical values table below, determine if the value of r is significant or not.

Degrees of Freedom	Critical Values
19	0.433
20	0.423
21	0.413
22	0.404
23	0.396
24	0.388

Select the correct answer below:

r is significant because it is between the positive and negative critical values.

r is significant because it is not between the positive and negative critical values.

r is not significant because it is between the positive and negative critical values.

r is not significant because it is not between the positive and negative critical values.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.

Based on the tables can you write or describe a summary for each? Thank you. Descriptive statistics of Sample Characteristics, Drug Use and Mental Health Bivariable Analyses Multivariable Analyses In this study we assess lifetime and recent drug use patterns among 261 heterosexually identified 18- to 25-year-olds through brief street intercept surveys conducted in New York City. Marijuana, hallucinogens, powder cocaine, and ecstasy were the most frequently reported drugs for both lifetime and recent use. Findings further suggest significant differences in lifetime use along the lines of gender, race=ethnicity, and school enrollment for various drugs. Males reported using significantly greater numbers of different drugs compared to females, as did those not enrolled in school compared to school enrollees. These data suggest that illicit drug use in emergent adulthood does not develop in a monolithic manner and synergies must be considered in relation to gender, school enrollment, and…
