True or false? A histogram and a relative frequency histogram, constructed from the same data, always have the same basic shape. Choose the correct answer below. O A. False. The two histograms can have very different shapes depending on the distribution of the data. O C. False. The histograms use different scales on the y-axis, resulting in completely different shapes. O B. True. They will both have the same shape and the same vertical scale. They will dffer only in...

Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.

Which of the following is NOT a true statement? A. Like the z distribution, the t distribution is bell shaped, symmetrical, and centers around 0. B. The t distribution is flatter and has fatter tails than the z distribution, which makes it more appropriate for the greater sample-to-sample variability in small samples C. Like the z distribution, there is only one t distribution. D. With sample sizes of 120 or more, the t distribution becomes virtually identical to the z...
