#5 The Canadian Veterinary Medical Association claims that the annual cost of medical care for dogs averages $120 with a standard deviation of $34 and for cats averages $145 with a standard deviation of $38. Complete parts a) through d). a) What is the expected difference in the cost of medical care for a randomly selected dog compared against a randomly selected cat? The expected difference is dollar(s). ( Round to the nearest dollar as needed.) b) What is the standard deviation of that difference? The standard deviation of the difference is $ (Round to the nearest cent as needed.) c) If the difference in costs can be described by a Normal model, what is the probability that medical expenses are higher for someone's dog than for her cat? The probability that medical expenses are higher for someone's dog than her cat is (Round to four decimal places as needed.ANSWER THE MISSING ANSWERS IN THE BOX. #1 An employer pays a mean salary for a 5-day workweek of 51200 with a standard deviation of 513?. On the weekends, his salary expenses have a mean of $550 with a standard deviation of 555. What are the mean and standard deviation of his total weekly salaries? The mean of his total weekly salaries is$ [Round to the nearest integer as needed} The standard deviation of his total weekly salaries is $ [Round to the nearest integer as needed} #2 A golfer keeps track of his score for playing nine holes of golf [half a normal golf round}. His mean score is 86 with a standard deviation of 11. Assuming that the second 9 has the same mean and standard deviation. what are the mean and standard deviation of his total score if he plays a full 18 holes? The mean of his total score is [Round to the nearest integer as needed} The standard deviation of his total score is (Round to one decimal place as needed} #3 An automatic filling machine in a factory fills bottles of ketchup with a mean of 17.8 oz and a standard deviation of 0.06 oz with a distribution that can be well modelled by a Normal model. What is the probability that a bottle of ketchup contains less than 17.7 oz? The probability that a ketchup bottle contains less than 17.7 oz is [Round to three decimal places as needed} #6 An investment website can tell what devices are used to access their site. The site managers wonder whether they should enhance the facilities for trading via smartphones so they want to estimate the proportion of users who access the site that way. They draw a random sample of 358 investors from their customers. Suppose that the true proportion of smartphone users is 34%. Complete parts b} through c} below b} What would be the mean of this sampling distribution? Mean = (Round to two decimal places as needed} c} What would be the standard deviation of the sampling distribution? Standard Deviation = Round to three decimal laces as needed
