Question 2
You may use the Normal distribution when you have the standard deviation of the sample and the sample size is higher than 30.
True
False
Question 3
With of 98 and a sample standard deviation of 10, the sample size of 16, and the population mean (μ) of a 100, the experimental t value is 0.8, and the P – value is between 0.10 and 0.25.
True
False
Q2. True, because if the sample size increases from more than 30 the distribution approaches a normal distribution ,
Q3. If the sample size is 16 then we use T distribution here,
Also given sample mean 98 and population mean is 100 and sample standard deviation is 10.
Now by t distribution formula
At t value -0.8 and Degree of freedom n-1=16-1=15
The p value associated with t is 0.218 which is beteeeb 0.10 and 0.25 but the t value is -0.8 hence the answer is
False

Assume standard IQ test scores follow a normal distribution with a population standard deviation of 14 points. In estimating the mean score of a sample group, we want to be 98% certain that we are within 4 IQ points of the true mean. Determine the required sample size.
QUESTION 1 1. The sample variance or the sample standard deviation are good approximate of the population variance or standard deviation? True or False QUESTION 2 1. The Central limit theorem states that the individual results or when n is 1 in an experiment that unique outcome follow a Normal Distribution? True or False QUESTION 3 1. In hypothesis testing alpha is the probability of being judged correct? True or False QUESTION 4 1. If the critical Z is ±...

The distribution of sample means for sample size n will have a standard deviation of. III. The distribution of sample means will approach a normal distribution as n approaches infinity.
For each of the following, find the mean and standard deviation of the sampling distribution of the sample mean. State if the sampling distribution is normal, approximately normal, or unknown. a. The population is skewed right with a mean of 4 and a standard deviation of 6. Many samples of size 100 are taken. b. The population is normal with a mean of 61 and a standard deviation of 9. Many samples of size 900 are taken. c. The population...
Question 1 The T distribution is used when you have the standard deviation of the population (σ). True False
1. Given a normal population which has a mean of 140 and a standard deviation of 21, find the probability that a random sample of 100 has a mean between 138 and 145. 2. If all possible samples of size n are drawn from an infinite population with standard deviation 8, then the standard error of the sample mean equals 1.0 if the sample size is 64. a. true b. false 3. You have completed an hypothesis test and determine...

Calculate 10t 25t* 50 75t and 90* percentiles once by converting to the standard Normal distribution, and again directly (using the non-standard Normal distribution) 2. What percentage of students score between 80 and 90 in the exam? 3. What percentage of students fail? 4. What percentage of students pass with A? 5. Generate a sample of size 16...
The difference between the T distribution and the standard normal (z) distribution decreases as the degrees of freedom increase. True False When estimating the number of responses to be collected in order to achieve a desired margin of error on a proportion, what value should be used for the population proportion if no estimate is available? Enter your answer as a decimal to 2 decimal places. A population is believed to have a standard deviation of 23.1. An analyst wants...
