4. In a study of caffeine and stress, college students indicate how many cups of coffee they drink per day and their stress level on a scale of 1 to 10 (with higher scores indicating greater stress). Data is collected from a sample of 10 students. The Pearson correlation coefficient for the relationship between these 2 variables is r = .43.

Harbucks coffee claims that the average amount of caffeine in cups of their coffee is 180 mg. Randy wishes to check the validity of this claim, and so he obtains a random sample of 49 cups of Harbucks coffee, from which he obtains a sample mean and standard deviation of 181 mL and 1.2 mL. Randy also notes that the sample data exhibit strong right skewness, so he suspects the population is also right skewed Does Randy have evidence to...

A study of 45 students revealed that they drank an average of 2.1 cups of coffee each day, and the sample standard deviation was found to be 1.1 cups of coffee. (a) Construct a 99% confidence interval for the average number of cups of coffee a college student drinks each day. (b) Construct a one-sided 98% confidence interval with a left endpoint for the average number of cups of coffee a college student drinks each day.

1) You study the number of cups of coffee consumer per day by students and discover that it follows a discrete uniform probability distribution with possible values for x of 0, 1, 2 and 3. What is the expected value of the random variable x? 2) The weight of cats is a continuous random variable and has a normal distribution with a mean of 10.27 pounds and a standard deviation of 4.26 pounds. What is the probability that a randomly...

. Average coffee consumption among graduate students is commonly known to be 3.89 cups per day. A graduate student took a sample of 10 fellow graduate students in her statistics class, and in the sample produced a mean of 4.02 cups per day and a standard deviation of .19. Because of this, she believes that the average is actually greater than what is commonly thought (3.89 cups per day). Do we believe the graduate student’s claim or the common belief?...

The BioPharm company has developed a stress test for college-aged students. Scores on the stress test are approximately normally distributed with a mean of 55 points and a standard deviation of 2 points. Scores of 58 points or higher indicate a high level of stress and are of concern to doctors. A random sample of college-aged students will be selected and each will be given this stress test. Answer the following questions based on the information given. 1. What is...
