We are interested in examining the IQ scores of college students versus the average population
IQ. We take a sample of 25 college students and have them take the WAIS. Our sample of
college students had an average WAIS of 110, and the known population mean for the WAIS is
100 with σ= 15.
a. What type of statistical test should we conduct (z score, one sample t test, independent
measures t test, repeated measures t test)? How do you know?
b. Are the data sufficient to conclude that our sample of college students scored
sufficiently higher than the population? Use a one-tailed test with a= .05
c. Please write a sentence explaining the results as they would appear in a research report.

Assume we are interested in looking at GRE scores of students admitted to graduate schools. Suppose GRE scores are Normally distributed with an average of 317 and a standard deviation of 11.5 points. Suppose we take a sample of 15 admitted students. What is the probability that the average GRE score from our sample of 15 students will be above 320?

It is known that nationally, students attending four-year colleges get an average of 6.75 hours of sleep per night, with a standard deviation of 1.7 hours. You are interested in seeing if students who attend commuter colleges (colleges where students must commute to school because there are no dorms on campus), such as John Jay College of Criminal Justice, differ significantly from this national average. Complete the following steps in order: What are the population mean and population standard deviation?...

A researcher is interested in whether students who are musicians have higher intelligence scores than those in the general population. The researcher predicts that playing a musical instrument is associated with higher intelligence test scores. The researcher selects a sample of 75 musicians from local high schools and gives them an intelligence test. She compares their average intelligence to that of students in the general population and finds that zobt = +1.92. This is a _____ test and the researcher...

A cognitive psychologist is interested in whether increasing reading speed improves comprehension. He has students complete a reading comprehension task before and after a six-week speed reading course. In the beginning of the study, a randomly selected group of B1 students scored an average of 102 points on the reading comprehension task. Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M_D is normal. He plans to use a repeated-measures t-test....

in comparing the engagement levels of first-year statistics students. In a previous nation-wide study, engagement levels were found to be normally distributed, with µ=60.00, σ=10.00. The lecturer collects a convenience sample of 50 first-year students and finds that her students have a mean engagement level equal to 75.54. What statistical procedure should be used, to test whether there is a significant mean difference in engagement levels between the lecturer’s first year students and the population average? a. One sample Z-test....

We know that, in the population, the average memory span (number of items a person can recall) is 7, with a standard deviation of 2. We want to know if the herb gingko biloba can really enhance a person’s memory. We get a sample of 25 students and have them take the herb for one month and then test their memory span. What null hypothesis would we test? What is the alternative hypothesis? We know that, in the population, the...

Researchers are interested in estimating the prevalence of smoking in college campuses. . Suppose the population prevalence is 25% and the research team has enrolled 300 current college students in their study, a. can we approximate with the normal distribution in this hypothetical example? Why or why not? b. What is the mean number of smokers in this sample? State also its variance. c. What is the probability of observing at least 100 students in this sample to be smokers?...
