A group of scientists is measuring an unknown quantity μER by repeatingindependent experiments. Let X be the value measured by the k-th experiment. Ifthe experiment is repeated for n times, the approximated value of μ, is given by thesample meanXn=X₁ + ... + XnN(The actual quantity is the (common) expected value of Xk.) They have a strongevidence that each X has an approximated standard deviation o= 3. Use centrallimit theorem to estimate how many experiments to repeat in order to be 98% surethat the approximated mean Xn is within 0.1 margin of error from the actual valuefe?

Given, Standard deviation is 3, confidence interval is 98% and margin of error is 0.1.

Suppose we are interested in studying a population to estimate its mean. The population is normal and has a standard deviation of σ = 16. We have taken a random sample of size n = 80 from the population. This is Sample 1 in the table below. (In the table, Sample 1 is written "S1", Sample 2 is written "S2", etc.) As shown in the table, the sample mean of Sample 1 is x=58.9. Also shown are the lower and upper limits of the 75% confidence interval for the population mean using this sample, as well as the lower and upper limits of the 95% confidence interval. Suppose that the true mean of the population is μ=60, which is shown on the displays for the confidence intervals. Press the "Generate Samples" button to simulate taking 19 more random samples of size n = 80 from this same population. (The 75% and 95% confidence intervals for all of the samples are shown in the table and graphed.) Then complete parts (a) through (c) below the table. 75% x 75% 95% 95% lower upper lower upper limit…
Patient satisfaction. Scores derived from a patient satisfaction survey are Normally distributed with μ = 50 and σ = 7.5, with high scores indicating high satisfaction. An SRS of n = 36 is taken from this population. What is the standard error (SE) of x for these data?
Imagine a distribution of sample means for samples of n = 35 selected from a population with a mean of μ = 40 and a standard deviation of σ = 12. In the box below, report three things for this distribution of sample means: its shape, its expected value, and its standard error. (Any of your three answers that are rounded numbers should be rounded to two decimal places.)
For a population with mean of μ X = 30 and standard deviation of σ X = 4 , the z-score corresponding to X = 28 is:

Bags of a certain brand of tortilla chips claim to have a net weight of 14 oz. Net weights actually vary slightly from bag to bag and are Normally distributed with mean u. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised, so he intends to test the hypotheses Ho: μ = 14, Ha: μ < 14. To do this, he selects 16 bags of this brand at random and determines the net weight of each. He finds the sample mean to be x = 13.88 and the sample standard deviation to be s = 0.24. Suppose in a similar test of 16 bags of these tortilla chips the P-value is 0.001. Further suppose that a is chosen to be 0.001. In that case, we would conclude that: Othere is not significant evidence that the mean net weight of the bags of chips is less than the advertised 14 oz. O there is not significant evidence that the mean net weight of the bags of chips is not less than the advertised 14 oz. O there is significant evidence that the…
Suppos are interested in studying a population to estimate its mean. The population is normal and has a standard deviation of G=23. We have taken a random sample of size 11=95 from the population. This is Sample 1 in the table below. (In the table, Sample 1 is written "S1", Sample 2 is written "S2", etc.) As shown in the table, the sample mean of Sample 1 is = 142.0. Also shown are the lower and upper limits of the 80% confidence interval for the population mean using this sample, as well as the lower and upper limits of the 95% confidence interval. Suppose that the true mean of the population is = 140, which is shown on the displays for the confidence intervals.

You have taken a random sample of size n = 12 from a normal population that has a population mean of μ = 90 and a population standard deviation of G = 4. Your sample, which is Sample 1 in the table below, has a mean of x=89.1. (In the table, Sample 1 is written "S1", Sample 2 is written "S2", etc.) (a) Based on Sample 1, graph the 80% and 95% confidence intervals for the population mean. Use 1.282 for the critical value for the 80% confidence interval, and use 1.960 for the critical value for the 95% confidence interval. (If necessary, consult a list of formulas.) • Enter the lower and upper limits on the graphs to show each confidence interval. Write your answers with one decimal place. • For the points (and ◆), enter the population mean, μ = 90. 85.0 S1 |+H 85.0 80% confidence interval 91.0 X +|||||||| x 80% 80% 95% 95% lower upper lower upper limit limit limit limit ? 89.1 ? ? ?
