A college professor conducted student evaluations at the end of a semester. One important question asked was, "Would you recommend this professor to a friend?” Fifty-four students responded using the following 1-to-5 rating scale. 1 = "absolutely not" 2 = "probably not” 3 = "no opinion" 4 = "probably yes" 5 = "absolutely yes" Student responses were recorded. "Blank" indicates that a student skipped this question on the evaluation. 4 #28: #1: Blank #10: #2: Blank #3: #4: Blank #5: #6: #7: #8: 4 #9: 5 4 5 2 # 11: #12: #13: #14: #15: # 16: #17: 3 Blank 5 Blank Blank 1 5 Blank # 19: #20: #21: #22: #23: #24: #25: #26: 4 #18: Blank #27: 1 2 #30: 1 #31: 3 Blank 5 #29: 5 Blank #32: #33: #34: #35: 1 #37: 5 Blank 4 1 5 4 5 #38: #39: #40: # 41: #42: #43: #44: #36: Blank #45: 2 #46: Blank 1 5 4 Blank #49: 5 #47: Blank #48: #50: #51: #52: Blank #53: 1 5 4 5 5 1 5 1 #54: Blank
I need help with something regarding this problem. The National Sleep Foundation recommends that adults aged 18 to 64 get an average of 8 hours of sleep per night. A survey of sleep hours was taken during a Statistics class. The data is listed below: 4, 5, 5, 5, 5.5, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10, 10 Do we have enough evidence at the 0.05 significance level to say that statistics students tend to get less sleep than the recommended average of 8 hours per night? How would I get the degrees of freedom?
Name 3) The Tire Rack, an online distributor of tires and wheels, conducts extensive testing to provide customers with products that are right for their vehicle, driving style, and driving conditions. In addition, the Tire Rack maintains an independent customer survey to help drivers help each other by sharing their long-term tire experiences (The Tire Rack website, August 1, 2016). The following data shows survey results (one to 10 scale with 10 being the highest rating) for 18 high performance all season tires. The variable tread wear rates quickness of wear based on drivers expectations, the variability dry traction rates the grip of a tire on a dry road, the variable steering rates the tires steering responsiveness, and the variable buy again rates the driver's desire to purchase the same tire again.

A new statistics book has been written and a faculty member and a student are asked to rank the new book and the other five best statistics books. How much do the student and professor agree on their assessment of the books (1 being the favorite, 6 being the least)? Use the data below to answer the following question:
Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…
