In a sample of 1995 adults from a certain region, 1505 reported that they currently receive cable or satellite TV service at home, 198 revealed that they have never subscribed to a cable/satellite TV service at home, and 292 admitted that they are "cord cutters," i.e., they canceled the cable/satellite TV service. One of the surveyed adults is randomly selected and his or her cable TV subscription status is determined. Complete parts a through d. a. Identify the sample points for this study. Choose the correct answer below. A. Currently receives cable/satellite TV service, Canceled cable/satellite TV service B. Currently receives cable/satellite TV service, Never received cable/satellite TV service C. Currently receives cable/satellite TV service, Never received cable/satellite TV service, Canceled cable/satellite TV service

Which of the followring statements are TRUE about the Hormal Distribution? Check all that apply. \( \square \) The distribution is symmetric with a single peak. \( \square \) about \( 95 \% \) of all data values lie within 1 standard deviation of the mean. \( \square \) The graph of the Hormal Distribution is bell-shaped, with tapering tails that never actually touch the horizontal axis. \( \square \) Data values farther from the mean are less common than data values closer to the mean. \( \square 50 \% \) of the data values lie at or above the mean. Data values are spread evenly around the mean. The mean, median and mode are all equal and occur at the center of the distribution.

In a normal distribution, a data value located 1.4 standard deviations below the mean has Standard Score: \( \mathrm{z}=-1.4 \) In a normal distribution, a data value located 2.3 standard deviations above the mean has Standard Score: \( \mathrm{z}=2.3 \) In a normal distribution, the mean has Standard Score: \( \mathrm{z}=\square \)

In a normal distribution, a data value located 1.2 standard deviations below the mean has Standard Score: \( \mathrm{z}=\square \) In a normal distribution, a data value located 2.4 standard deviations above the mean has Standard Score: \( \mathrm{z}=\square \) In a normal distribution, the mean has Standard Score: \( \mathrm{z}=\square \)

Which of the following statements are TRUE about the Normal Distribution? Check all that apply. The graph of the Normal Distribution is bell-shaped, with tapering tails that never actually touch the horizontal axis. \( 50 \% \) of the data values lie at or above the mean. about \( 95 \% \) of all data values lie within 1 standard deviation of the mean. The mean, median and mode are all equal and occur at the center of the distribution. Data values are spread evenly around the mean. Data values farther from the mean are less common than data values closer to the mean.

Consider the Standard Normal distribution. The mean is always \( \square \) and the standard deviation is always
