SHOW ILPO/Instructions According to the Bureau of Labor Statistics, the mean salary for registered nurses in Kentucky was $55.959. The distribution of salaries is assumed to be normally distributed with a standard deviation of $5,883. Someone would like to determine if registered nurses in Ohio have a greater average pay. To investigate this claim a sample of 277 registered nurses is selected from the Ohio Board of Nursing, and each is asked their annual salary. The mean salary for this...

A news report states that the 95% confidence interval for the mean number of daily calories consumed by participants in a medical study is (2030, 2200). Assume the population distribution for daily calories consumed is normally distributed and that the confidence interval was based on a simple random sample of 19 observations. Calculate the sample mean, the margin of error, and the sample standard deviation based on the stated confidence interval and the given sample size. Use the t distribution...

A 95% confidence interval for a population mean was calculated. The sample mean was found to be 34.5 and the MOE was found to be 4.06 giving us a confidence interval of 34.5±4.06 or equivalently written as 30.44 to 38.56. (a) For the hypotheses H0:?=30 Ha:??30, would you reject the null hypothesis at the 5% level of significance (i.e. ? = 0.5)? (Type: YES or NO or CANNOT TELL): (b) For the hypotheses H0:?=41 Ha:??41, would you reject the null...

Explain what "95% confidence" means in a 95% confidence interval. What does "95% confidence" mean in a 95% confidence interval? A. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 95 of the intervals to include the parameter and 5 to not include the parameter. B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 95%....
