statistics students believe that the average score on the first statistics test is 65. A statistics instructor thinks the average score is higher than 65. he samples ten statistics students and obtains the scores 65;65;70;67;66;63;63;68;72;7. he performs a hypothesis test using a 5% level of significance. the data are from a normal distribution. A) use these data to compare a 95% confidence interval for u. B) is there enough evidence to reject the claim? 4. it has been reported that...

Statistics students believe that the mean score on a first statistics test is 65. The instructor thinks that the mean score is higher. She samples 10 statistics students and obtains the scores: Grades 73.5 68.4 65 65 63.9 68.4 64.3 66.5 61.9 69 Test grades are believed to be normally distributed. Use a significance level of 5%. State the standard error of the sample means: (Round to four decimal places.) State the test statistic: t=t= (Round to four decimal places.) State the...

5. A class of undergraduate criminal justice students took a test and the average score of the class was 280 with a standard deviation equal to 40. What minimum score does a student need to obtain in order to pass the exam? (60th percentile and above) What is the minimum score a student need to receive in order to get at least a B (80th percentile) at the exam?

A: You recently took a statistics class in a large class with n = 500 students. The instructor tells the class that the scores were Normally distributed, with a mean of 7 2 (out of 100 ) and a standard deviation of 8 , but when you talk to other students in the class, you find out that more than 30 students have scores below 45 . That violates which rule for the Normal distribution? the 30–60–90 rule the 1–2–3...

I asked 100 students to complete a statistics test. the mean score on the test was 30 points with a standard deviation of 5 points. using this information and the normal distribution, calculate the following: [want to check my overall answers and help with the process of some] thank you a. what is the probability a student earned a score of 45 points or less? P(score <45 points) i got 0.9987 b. what is the probability a student earned a...

A large group of students took a test in Statistics and the final grades have a mean of 70 and a standard deviation of 10. If we can approximate the distribution of these grades by a normal distribution, what percent of the students a) scored between 50 and 90? b) scored higher than 90? c) should pass the test (grades≥50) d)non of the above d) should fail the test (grades<50)?

The score on an test from a certain statistics class, ?, is normally distributed with ?=80.8 and ?=8.3. NOTE: Assume for the purpose of this problem that the score is a continuous variable. A score can thus take on any value on the continuum. (In real life, scores are often treated as if they were continuous values but are actually discrete in most cases.) (a) Write the event ''a score over 65.8'' in terms of ?: . (b) Find the probability...

A first year statistics class took part in a simple experiment. Each person took their pulse rate. They then flipped a coin and, if it came up tails, they ran in place for one minute. Everyone then took their pulse a second time. Of the 92 students in the class, 32 ran in place. In repetitions of this experiment, the number that run in place should have a binomial distribution with n = 92 trials and probability of success p...

In a statistics class, 8 students took their pulses before and after an exam. The pulse rates (beats per minute) of the students before and after the exam were obtained separately and are shown in the table. Treat this as though it were a random sample of statistics students. Test the hypothesis that the mean of statistics students' pulse rates is higher after an exam using a significance level of 0.05. Do the 5-step hypothesis test and submit an image...

In a psychology class, 59 students have a mean score of 98 on a test. Then 16 more students take the test and their mean score is 62.8. What is the mean score of all of these students together? Round to one decimal place. mean of the scores of all the students = 57 randomly selected students were asked how many siblings were in their family. Let X represent the number of pairs of siblings in the student's family. The...
