According to a standard normal table, the area under the standard normal curve to the left of 0.89 is 0.8133. Without consulting a standard normal table or using technology, determine the area under the standard normal curve to the left of - 0.89. The area to the left of z = - 0.89 is.

Property 3: Approximately of all possible observations lie within three standard deviations to either side of the mean.For a variable with a density curve, what is the relationship between the percentage of all possible observations of the variable that lie within any specified range and the corresponding area under its density curve? Choose the correct answer below. A. They are equal (at least approximately) when the area is expressed as a percentage. O B. They are exactly equal. O C. They are not related. O D. They can be similar but do not represent the same value.A normal probability plot of data from a sample of a population is shown to the right. Assess the normality of the variable under consideration. Normal score 15 20 Choose the correct answer below. O A. The relationship is approximately linear, so the variable under consideration is probably normally distributed. O B. The relationship is not linear, so the variable under consideration is probably not normally distributed. O C. The relationship is approximately linear, so the variable under consideration is probably not normally distributed. O D. The relationship is not linear, so the variable under consideration is probably normally distributed.Sketch the graph that shows Zo.36 and then determine zo.36- Click here to view page 1 of the normal distribution table.

Choose the correct answer below. A. The standard normal curve is sometimes referred to as the z-curve because it is common to use the variable z for normally distributed variables. O B. The standard normal curve is sometimes referred to as the z-curve because it forms a shape that resembles the letter z. O C. The standard normal curve is sometimes referred to as the z-curve because it has a normal distribution with a mean of 0 and standard deviation of z. O D. The standard normal curve is sometimes referred to as the z-curve because the standard normal curve is the associated normal curve for a standardized normally distributed variable, and a standardized normal variable is labeled z.How is a normal probability plot used to detect outliers? Choose the correct answer below. O A. All observations are used to construct the normal probability plot, and any observations that have a normal score greater than 2 in magnitude may be outliers. O B. All observations are used to construct the normal probability plot, and any observations that fall well outside the overall pattern of the data may be outliers. O C. All observations are used to construct the normal probability plot, and any observations that do not fall on a straight line may be outliers. O D. All observations are used to construct the normal probability plot, and any observations above 0 may be outliers.A commuter train arrives punctually at a station every half hour. Each morning, a commuter named John leaves his house and casually strolls to the train station. The time, in minutes, that John waits for the train is a variable with density curve y = 27 for 0
