Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults found that 6% say their favorite sport is auto racing. You randomly select 400 adults and ask them to name their favorite sport. Complete parts (a) through (d). Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correct answer below. O A. No, because np < 5. B. No, because ng < 5. C. Yes, because both np 25 and ng 25. (a) Find the probability that the number of people who say auto racing is their favorite sport is at most 30. (Raund to four decimal places as needed.)

omework Assessment A Dashboard + ent/showtest.php The average final exam score for the statistics course is 76%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is different. The final exam scores for the 12 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 70, 60, 54, 59, 73, 87, 52, 86, 56, 75, 52, 73 What can be concluded at the the a=0.10 level of significance level of significance? a.

A survey was conducted two years ago asking college students their top motivations for using a credit card. You think this distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a = 0.025. Complete parts (a) through (d). Response Old Survey % 29% New Survey Frequency, f Rewards 110 Low rates Cash back Discounts 23% 96 21% 109 7% 46 Other 20% 64 O B. The distribution of motivations is 110 rewards, 96 low rate, 109 cash back, 46 discounts, and 64 other. O C. The distribution of motivations is 29% rewards, 23% low rate, 21% cash back, 7% discounts, and 20% other.

Jamie’s Intro to Biology professor tells the class that on the first exam, the mean score is a 70, but the median score is an 84. What does this tell you about the skewness of the distribution? What measures of center and spread would you use to describe this distribution? a. The distribution is skewed left, so we should use the mean and the median to describe the distribution. b. The distribution is skewed left, so we should use the median and the IQR to describe the distribution. c. The distribution is skewed right, so we should use the median and the IQR to describe the distribution. d. The distribution is symmetric, so we should use the standard deviation and the IQR to describe the distribution. e. The distribution is skewed right, so we should use the mean and the IQR to describe the distribution.

Ti A fitness instructor at a large gym would like to know if the individuals that take fitness classes in the morning tend to get in a greater number of steps than individuals that take evening fitness classes. She selects a random sample of 10 individuals that take fitness classes in the morning and 10 individuals that take fitness classes in the evening. She gives each person a step-counting At 10 device to wear for one week. At the end of the week she collects the devices and calculates the mean and standard deviation of the number of steps taken by the individuals in each group. Let uM = the true mean number of steps taken by all individuals who take fitness classes in the morning and HE = the true mean number of steps taken by all individuals who take fitness classes in the evening. What are the appropriate hypotheses for this test? O Ho: HM - HE = 0; Ho: HM - HE 0; H: HM - HE = 0 O Ho: HM HE = 0; Ha: HM - HE > 0 O Ho: HM HE < 0; H HM - HE = 0 O Ho: HM - HE - 0: H HM - HE #0
