What is the probability of the two problem
A simple random sample of size n=10 is obtained from a population that is normally distributed with a mean of 40 and a standard deviation of 3. Is the sampling distribution normally distributed? Why? Yes, the sampling distribution is normally distributed because the population is normally distributed. Yes, the sampling distribution is normally distributed because the population mean is greater than 30. No, the sampling distribution is not normally distributed because the population is not normally distributed. No, the sampling distribution is not normally distributed because the sample size is less than 30.
Please help Determine the probability mass function for the scores that can be obtained by the throwing of two fair dice.
You find 6 statements below. Each statement is either true (T) or false (F) (write yourchoice in the table). 1) In a probability model, all possible outcomes together must have a probabilityof 1.2) A density curve describes the probability distribution of a discrete randomvariable.3) Outliers do not have a large effect when we calculate the mean.4) The probability of success for binomial distribution must remain the same foreach trail.5) In the Normal distribution with mean μ and standard deviation σ, approximately95% observations fall within ± 2σ of the mean μ.6) Since the median is the middle value of a data set it must always be smaller thanthe mean.
If the sample mean falls within the central 95% of scores in the sampling distribution: We retain the null hypothesis (H0) It definitely occurred due to chance All of these are correct The sample probably came from a populationi other than the population we know about
Are these statements true or false? High chi-square values indicate a high probability that the observed deviations could be due to random chance alone Low chi-square values indicate a low probability that the observed deviations could be due to random chance alone.
6- The variance of the sum of the random variables equals the sum of the variances if the random variables are uncorrelated. True O False
if we take samples from the population that has an unknown probability distribution, the sampling distribution will still be approximately normal even if the sample size is small because of the central limit theorem True or False
when a population is uniformly distributed (flat), is the sampling distribution of xbar for random samples of 2 observations roughly normal, strongly skewed, or triangular?
Is it true ore false
What is the Central Limit Theorem? It is always true that as the sample size, n, increases, the distribution of the sample means will be approximately normally distributed. Explain
When we want to test a claim about two population means, most of the time we do not know the population standard deviations, and we assume they are not equal. When this is the case, which of the following is/are not true? The samples are dependent The two populations have to have uniform distributions Both samples are simple random samples Either the two sample sizes are large or both samples come from populations having normal distributions or both of these conditions satisfied.
