In the normal distribution the area to the right of the mean is always 50%. True...
The area to the left of the mean on a standard normal distribution curve will always be _________ because the curve is symmetrical. Select one: a. 95% b. 50% c. 100% d. 68%
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...
If I has a normal distribution, then 7 always has a normal distribution. True False Under what condition does the sample mean ī not have a normal distribution? Population is not normal but the sample size n > 30. Population is not normal and sample size n <30. Population is normal. The Central Limit Theorem for a sample mean (@) is very important in Statistics because it states that for large sample sizes, the population distribution is approximately normal. for...
The normal distribution is symmetrical, so that 50% of the scores are above the mean and 50% of the scores are below the mean. Question 3 options: a) True b) False
Consider the normal distribution with mean 50 and standard deviation 5. Find the area under the normal curve and above the interval [58,0o) on the horizontal axis Click the icon to view the area under the standard normal curve table The area under the normal curve for the interval [58,00) is Enter your answer in the answer box and then click Check Answer.
In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...
Assuming a normal distribution with a true mean of 50 Newtons and a standard deviation of 1.8 Newtons, what is the probability (in percentage) that future measurements will fall below 48.58 Newtons?
the mean of the sampling distribution of x-bar is not always equal to the mean of the sampled poulation. True or False?
The normal distribution is defined by two parameters - the mean and the median. a. True b. False
In the normal distribution about 95% of the area lies within the three standard deviations from the mean. TRUE OR FALSE
