Give the meaning of outlier. Does it affect the measures of central tendency? Give the meaning of outlier. Select the correct choice below. A. The outlier of a set of numbers is found by adding all the values in the set and dividing by the number of values. B. The outlier of a data set is the value (or values) that occurs most often in a set. C. The outlier is an observation that is numerically distant from the rest of the data. O D. The outlier is a kind of "middle" number. To find the outlier, first arrange the values in numerical order from least to greatest. For an odd number of values, the outlier is the middle value in the list. For an even number of values, the outlier is the mean of the two middle values. Does it affect the measures of central tendency? Select the correct choice below. O A. The outlier does not affect any of the measures of central tendency. O B. The outlier does affect the measures of central tendency, especially the mean.

The technology committee has stated that the average time spent by students per lab visit has increased, and the increase supports the need for increased lab fees. To substantiate this claim, the committee randomly samples 12 student lab visits and notes the amount of time spent using the computer. The times in minutes are shown in the table to the right. Complete parts a and b. Time 74 134 53 10 71 51 70 60 62 52 68 54 Are any of the observations outliers? Explain. O A. The histogram shows that there are no outliers. The conditions for inference are satisfied. O B. The histogram shows that there is one extreme outlier. Since the sample size is large enough, the conditions for inference are okay. Vc. The histogram shows two extreme outliers. With these values included, the conditions for inference are violated. b) The previous mean amount of time spent using the lab computer was 54 minutes. Find a 90% confidence interval for the true mean. What do you conclude about the claim? If there…
