A doctor is interested in the time it takes broken bones of a given size and type to heal. A random sample of 17 single arm breaks occurring in victims in their twenties took an average of 53 days to heal with a standard deviation of 5 days. Is there sufficient evidence to say the mean healing time is less than 56 days? Use alpha

= 0.05 to test this claim. Assume normality.

We are interested in studying whether there is a difference in the time it takes for patients to recover after surgery for two given hospitals. A simple random sample of cardiac surgery patients were taken from each hospital. The results were summarized in the table below. It shows the hospital one attended (Hospital A vs Hospital B), and the average length of stay (measured in days) for patients after cardiac surgery. n Average Length of Stay (in days) Sample Standard...

An analyst at Carnival Cruise Lines is interested in the time it takes for a room service order to go from time of order to time of delivery. In order to do this, she takes a sample of 49 random guests and finds that their average time to delivery was 11.2 minutes and that the sample standard deviation was 3.5 minutes. Calculate a 95% Confidence Interval around the mean.

A researcher is interested in a possible relationship between height and the time it takes to run a 100 meters. With a random sample of 57 people, the researcher finds a Pearson correlation coefficient r = − 0.492. Group of answer choices A. There is a very strong correlation between these variables. As height increases, generally the 100-meter run time decreases. B. There is a very strong correlation between these variables. As height increases, generally the 100-meter run time increases...

A researcher is interested in the mean amount of time it takes people to complete a personality questionnaire. He selects 40 people at random and calculates the mean amount of time to be 20.4 min with a variance of 17.64 min2 . a) Define the parameter of interest. b) Define the random variable of interest. c) Name the distribution required to calculate confidence intervals. (Check the relevant criteria.) d) Construct a 98% confidence interval for the true mean amount of...

Another doctor from Facebook claims that the medication Remdesivir can reduce the time it takes to recover from COVID-19. He states that of the 300 people who got it, 80% of the patients were “recovered” by 8 days. Of the 300 people who didn’t get it, 60% of the patients were recovered by 8 days. So, since you know that doctors are not very good with statistics, you decide to test his data and see if it is effective. What...

Suppose you are interested in measuring the amount of time, on average, it takes you to make your commute to school. You've estimated that the average time is 35.68 minutes with a standard deviation of 6.17 minutes. Assuming that your estimated parameters are correct and the commute time is normally distributed, what is the probability that the average commute time of 11 random days is greater than 36.86 minutes? Question 8 options: 1) 0.2629 2) 0.7371 3) 0.5758 4) 0.8246...

A group of researchers hypothesize that broken bones will take longer to heal among smokers versus nonsmokers. They test this question with a sample of 20 smokers, where the average time to heal was 32 days (SS = 1161), and a sample of 45 nonsmokers, where the average time to heal was 21 days (SS = 1179). Use the critical-value approach for the appropriate statistical test (where α = .05) to determine if there is a significant difference in bone...

9. You are interested in studying the average duration of time (in minutes) it takes Temple University students to drive to campus. The conventional wisdom is that on average it takes students 30 minutes to drive to campus. To examine this, you randomly sample n=15 students and record this information. From the sample, you compute a sample mean of 26 with a sample standard deviation of 6. Conduct a two-tailed hypothesis test with 95% confidence. Then, construct a 95% confidence...

A large university is interested in learning about the average time it takes students to drive to campus. The university sampled 238 students and asked each to provide the amount of time they spent traveling to campus, the average and standard deviation were 21.5 and 4.32 respectively. This variable, travel time, was then used conduct a test of hypothesis. The goal was to determine if the average travel time of all the university's students differed from 20 minutes. Use a...

The amount of time it takes for a student to complete a statistics exam is given by a random variable that is uniformly distributed between 28 and 61 minutes. A student is selected at random. Find the probability of the following events. In each case, give exact answers or round to at least three decimal places. The student’s time was between 34 and 39 minutes The student’s time was less than 34 minutes The student’s time was between 39 and...
