A random sample of students was asked for the number of semester hours they are taking this semester. The standard deviation was found to be 4.7 semester hours. a) how many students should be included in the sample to be 90% sure that the sample mean is within 1 semester hour of the population mean for all students at this college?
I will leave a LIKE if everything is answered correctly like I have asked. The data below was collected from Math 13 students. They were asked how many units they were taking this semester and to rate their math anxiety level, on a scale from 0 to 10 For each hypothesis test, provide the claim, critical values, test statistic and conclusion 5) Divide the data into two groups: those with 0-5 math anxiety and those with 6-10 math anxiety. Test...
Question 1. Thirty graduate students were asked how many credit hours they were taking in the current quarter. Download the available data: Calculate the mean, median, standard deviation, variance, and range for this sample using Excel. Write a sentence explaining what each measure means. What is the standard error of the mean based on the data? What would be the best point estimate for the population credit hours? (“Population” refers to all graduate students’ credit hours in the universe.) What...

1. Several BC students are asked how many courses they took last semester. 77 answered "none", 33 said "one, 24 said "wo", and 6 responded with three or more. Find the probability that a randomly selected student from this group took three or more courses last semester. Would it be unlikely for one of these students to have taken three or more courses last semester? Why or why not? Round your final answer to 3 significant digits.
At the beginning of a semester a group of students who were US residents admitted through the regular admissions process and who were taking the same courses were selected based on their high use of social media and the similarities of their college GPA's. The selected students were randomly assigned to one of 2 groups: At the beginning of a semester a group of students who were US residents admitted through the regular admissions process and who were taking the...
1. A group of students from two schools was asked how many hours of television they had watched last week. Here are their responses School A School B 8 7 1 12 20 10 6 3 7 7 6 7 4 4 8 8 13 17 17 9 Calculate the mode, median, and mean for each distribution. Why is only the mean different for the two samples? [Hint: Think about which measures of central tendency are most sensitive to outliers.]
