You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 36 business days, the mean closing price of a certain stock was $112.10. Assume the population standard deviation is $10.86. a)The 90% confidence interval is ______ b)The 95% confidence interval is _______ c)Which interval is wider? Choose the correct answer below. 1) The 90% confidence interval 2)The 95% confidence interval Interpret the results. A). You can be 90% confident that the population mean price of the stock is outside the bounds of the 90% confidence interval, and 95% confident for the 95% interval. B). You can be certain that the closing price of the stock was within the 90% confidence interval for approximately 32 of the 36 days, and was within the 95% confidence interval for approximately 34 of the 36 days. c). You can be 90% confident that the population mean price of the stock is between the bounds of the 90% confidence interval, and 95% confident for the 95% interval. D). You can be certain that the population mean price of the stock is either between the lower bounds of the 90% and 95% confidence intervals or the upper bounds of the 90% and 95% confidence intervals.

Remember the eye blink classical conditioning scenario we discussed in class, where a tone was paired with a puff? This type of learning would strengthen synapses in the brain. Where would these synapses be most likely to occur? A) reciprocal connections between the tone-hearing and eye-puff-detecting detecting neurons. B) where neurons activated during tone hearing and neurons activated by air puff-sensing project their axons on neurons that cause blinking. C) only within the tone-hearing neurons. D) only within the eye-puff-detecting neurons.

One year Perry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of 3.17. Also, Susan had the lowest ERA of any female pitcher at the school with an ERA of 3.16. For the males, the mean ERA was 4.242 and the standard deviation was 0.873. For the females, the mean ERA was 3.949 and the standard deviation was 0.874. Find their respective Z-scores. Which player had the better year relative to their peers, Perry or Susan? (Note: In general, the lower the ERA, the better the pitcher.) a)Perry had an ERA with a Z-score of b)Susan had an ERA with a Z-score of

List five properties of the F-distribution. CODOR Determine the first of the five properties. The F-distribution is a family of curves, each of which is determined by two types of degrees of freedom: the degrees of freedom corresponding to the variance in the numerator, denoted by dif.n. and the degrees of freedom corresponding to the variance in the denominator, denoted by d.f.p Determine the second of the five properties. The F-distribution is positively skewed and therefore the distribution is not symmetric. Determine the third of the five properties. The total area under each F-distribution curve is equal to 1 (Type an integer or a decimal.) Determine the fourth of the five properties. Choose the correct answer below. A. All values of F are greater than or equal to 0. © B. All values of F are less than or equal to 0. OC. All values of F are between - 1 and 1. D. All values of F are between 0 and 1. Determine the fifth of the five properties. For all F-distributions, the mean value of F is approximately equal to (Type an integer or a decimal.)
