For a normally distributed population with a mean of 35 and a standard deviation of 7.5, if a sample of 50 is taken from the population, what is the probability that the sample mean will be greater than 36.5?
Find the probability that the mean of a random sample of 25 elements from a normally distributed population with a mean of 90 and a standard deviation of 60 is larger than 100.
For a normally distributed population with a mean of 35 and a standard deviation of 7.5, if a sample of 50 is taken from the population, what is the probability that the sample mean will be between 35 and 37.5?
Random samples of size 55 are taken from a normally distributed population that has 425 elements, a population mean of 20, and a population standard deviation of 7. What is the standard deviation of the sampling distribution of the sample means?
A normally distributed population has a mean of 600 and a standard deviation of 60. a. Determine the probability that a random sample of size 25 selected from this population will have a sample mean less than 579. b. Determine the probability that a random sample of size 16 selected from the population will have a sample mean greater than or equal to 636.
A random sample of size n = 25 is obtained from a normally distributed population with population mean μ =200 and variance σ^2 = 100. a) What are the mean and standard deviation of the sampling distribution for the sample means? b) What is the probability that the sample mean is greater than 203? c) What is the value of the sample variance such that 5% of the sample variances would be less than this value? d) What is the...
on Help A sample of 51 values is taken from population that is normally distributed with a mean of 341 and a standard deviation of 52. Find the probability that the sample standard deviation is less than 46. PCS < 46) = 0 (Round to four decimal places as needed.)
The weight of the contents of a type of box of cereal is normally distributed with population mean μ = 30 ounces and population standard deviation σ = 3.2 ounces. A random sample (size n = 25) is taken. What is the probability that the sample mean is less than 31.74 ounces?
Suppose nine items are sampled from a normally distributed population with a mean of 116 and a standard deviation of 17. The nine randomly sampled values are shown in the table. 145 111 114 141 117 143 100 71 102 Calculate the probability of getting a sample mean that is smaller than the mean for these nine sampled values. The probability that a sample mean is smaller than the mean for these nine values = (Round to four decimal places...
saved Question 2 (1 point) From a population of 200 elements, the standard deviation is known to be 14. A sample of 16 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is 3.5 less than 3.5 less than 2 Save
