Data indicates that adolescent girls tend to experience a drop in self-esteem. To evaluate this result, a researcher obtains a sample of N = 36 adolescent girls, all 13 years old. A self-esteem measure is administered to each participant and the average score for the sample is X =68. It is known that the distribution of self-esteem scores for the population of pre-teen girls is normal with mean 80 and standard deviation 10. (a) Compute a 95% confidence interval for µ, the population mean self-esteem score for adolescent girls. (b) Compute Cohen’s d to estimate the size of the described effect. (c) Perform a hypothesis test to decide whether the mean self-esteem score for adolescent girls is significantly different from the mean self-esteem score for pre-teen girls. (d) Compute and interpret a Bayes factor for the model (either H0 or H1) with the best predictive adequacy. (e) Compute and interpret the posterior model probability for the winning model chosen in part (d).
The calibration of a scale is to be checked by weighing a 10-kg test specimen 25 times. Suppose that the results of different weighings are independent of one another and that the weight on each trial is normally distributed with = 0.2 kg. Let μ denote the true average weight reading on the scale. (a) What hypotheses should be tested? (b) What is the p-value when = 9.85? What would you conclude at significance level a = 0.01?

The viscosity of a liquid detergent is supposed to average 800 centistokes at 25°C. A random sample of 16 batches of detergent is collected, and the average viscosity is 812. Suppose we know that the standard deviation of viscosity is σ = 25 centistokes. (a) What is the P-value for the test? (b) Find a 95 percent confidence interval on the mean.
A simple random sample of size 10 has a mean of 65.0 and a sample standard deviation of 8.0. A student would like to test the null hypothesis, ?0:?=70.0H0:μ=70.0, against the alternative, ?1:?<70.0H1:μ<70.0. Construct a confidence interval corresponding to this test at significance level ?=10%α=10%. Give your answer precise to two decimal places. lower limit = upper limit =
An SRS of 400 high school seniors gained an average of x = 21.87 points in their second attempt at the SAT Mathematics exam. Assume that the change in score has a Normal distribution with standard deviation o = 48.66. We want to estimate the mean change in score µ in the population of all high school seniors. (a) Using the 68-95-99.7 Rule or the z-table (Table A), give a 95% confidence interval (a, b) for u based on this sample. (Enter your answers rounded to three decimal places. If you are using CrunchIt, adjust the default precision under Preferences as necessary. See the instructional video on how to adjust precision settings.) a: b: (b) Based on your confidence interval in part (a), how certain are you that the mean change in score u in the population of all high school seniors is greater than 0? O The upper endpoint of the interval is larger than 0, so we are 95% certain that the mean change in score in the population of all high school seniors is greater than 0. O We cannot be…

An NHANES report gives data for 647 women aged 20–29 years. The BMI of these 647 women was x= 25.8. On the basis of this sample, we want to estimate the BMI u in the population of all 20.6 million women in this age group. We treated these data as an SRS from a Normally distributed population with standard deviation o = 7.1. (a) Give three confidence intervals for the mcan BMI u in this population, using 90%, 95%, and 99% confidence. Enter the lower and upper bound for the 90% confidence interval. (Enter your answers rounded to two decimal places. If you are using Crunchlt, adjust the default precision under Preferences as necessary.

The adhesive strength of medical monitoring device has a known standard deviation of 0.55 dyne cm. Tests on the first five prototypes of a new model yielded the following values of adhesive strength: 2.96, 5.67, 2.76, 1.26 and 4.21 dyne-cm'. a. What is the 95% confidence interval for the mean adhesion? b. If the manufacturer wants the confidence interval to be no wider than 0.62 dyne-cm2, how many 1. observations should they take?
