Which of the following is true about the distribution of IQ scores?
1)The area under its bell-shaped curve is 10.
2) It is a nonstandard normal distribution.
3) Its distribution is skewed to the right.
4) Its distribution is skewed to the left.
solution
the following is true about the distribution of IQ scores
as we know that total area under the bell-shaped curve is 1. so it can't be 10 and not skewed to the right and left
option 2 is true ,it is a nonstandard normal distribution
so,The distribution of IQ scores is a nonstandard normal distribution

In a standard normal distribution bell curve, the proportion of the total area which must be to the left of the mean is and the total area under the curve is A: between 0.25 and 0.60; 0.50 and 1.20 B: exactly 0.50; 1 C: less than 0.50 if the distribution is skewed to the left; 1 D: more than 0.50 if the distribution is skewed to the right; 1
Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. There's a graph (bell-shaped curve graph) depicting .99 shaded area to the left of x.
Respond True or False to each of these statements. The total area under the normal distribution is equal to 1. As the sample size increases, the distribution of the sample statistics becomes more consistent. Sampling variability refer to a variability of parameters. A sampling distribution describes a distribution of sample statistics. All variables that are approximately normally distributed can be transformed to standard z-scores. The z-value corresponding to a datum below the mean is always negative. The area under the...
