An Article in the Journal of Sports Science (1987, Vol. 5, pp. 261-271) presents the results of an investigation of the hemoglobin levelof Canadian Olympic ice hockey players. A random sample of 20 players is selected and the hemoglobin level is measured. Theresulting sample mean and standard deviation(gdl) are x=15.23 and s=0.6117. Use this information to calculate a 95% two-sidedconfidence interval on the mean hemoglobin level and a 95% two-sided confidence interval on the variance. Assume the data arenormally distributed. Round your answers to 2 decimal places i.e., 0.00. Provide all the the necessary solutions.Blank 1sus Blank 2Blank 3 s 02 < Blank 4

A psychologist is studying the effects of lack of sleep on the performance of various perceptual-motor tasks. After a given period of sleep deprivation, a measurement of reaction time to an auditory stimulus was taken for each of 36 adult male subjects. The reaction times (in seconds) are summarized as follows:x = 1.82, S=0.22. Find a 99% confidence interval for the mean reaction time for sleep-deprived male subject
a. interpret the corresponding 95% confidence intervals for both Birth weight and Age. b. What is the predicted average SBP of an infant born with birth weight 8lbs (128oz) measured at 3 days old? c. Calculate the Pearson correlation between Age and Birth weight, and test if this correlation is significant at the 0.05 level. Does this answer surprise you, why or why not?
A researcher wants to asses the self-discipline levels among undergraduate and graduate students. A random sample of 300 undergraduate students was selected with average score of 184 and standard deviation of 16 ( group 1). Also , a random sample of 350 graduate students was selected with average score of 153 and standard deviation of 21 ( group 2). Is this enough evidence to conclude that undergraduate students score less, on average than the graduate students. [ assume that the population variances are equals]. i.
