Take a Test - Muhamed Shuha X ms Muhamed Shuhail Muhamed Yaseen 5 | 5/6/18 12:05 AM bmit Quiz *0 Clifford likes dogs. He wondered how much dog owners spend on their dogs in a year. He hypothesized that dog owners spend more than $1000 a year on their dogs, on average. He sampled 75 dog owners in a local community and found that
these 75 dog owners spent an average $1075 on their dogs in a year. Suppose “X = $175. Assume that these 75 dog owners are representative of all dog owners in terms of amount spent on their dogs in a year. The z-statistic in this problem is 3.71. What does this mean? Choose the correct answer below. 0 A. The sample mean, $1075, is 3.71 times larger than the hypothesized value of the population mean. 0 B. The standard deviation of the distribution of sample means is 3.71 standard deviations from the population mean of $1000. 0 C. The standard deviation of the sample data is 3.71. O D. The standard deviation of the distribution of sample means is 3.71. O E. The sample mean, $1075. is 3.71 standard deviations greater than the population mean, which is $1000 if the null hypothesis is true. Click to select your answer. ®
