Butz et al. evaluated the duration of benefit derived from the use of noninvasive positive-pressure ventilation by patients with amyotrophic lateral sclerosis (ALS) on symptoms, quality of life and survival. ALS, aka Lou Gehrig's Disease, is a degenerative disease of the motor neurons. One of the variables of interest is partial pressure of arterial carbon dioxide (PaCO2). The values below (measured in mm Hg) reflect the results of baseline testing on 20 of the 30 subjects in the study, as established by arterial blood gas analyses. (Am. J Med.

Hint: To create a histogram, you would first need to decide on the bin ranges. Since the data is numerical and ratio,…
Explain why a high R-squared is not an indication that an estimated OLS coefficient β^1 from a model: y = β0 + β1x1 + ⋯ + βkxk + u is a causal estimate of the impact of x1 on y. What other factors are relevant to assess whether β^1 is a causal estimate?
A random sample of 100 students at a high school was asked whether they would ask their father or mother for help with a financial problem. A second sample of 100 different students was asked the same question regarding a dating problem. If 43 students in the first sample and 47 students in the second sample replied that they turned to their mother rather than their father for help, test the hypothesis of no difference in the proportions. Use α = 0.02. Identify the critical value(s). 2.33 ±2.33±2.33 ±2.05±2.05 2.05
A clinical trial is being conducted in order to determine the efficacy of a new drug that will be used to treat rheumatoid arthritis. The efficacy of the medication will not only be determined by the physical improvement of symptoms but will also be determined by using a blood test to examine the concentration of C-reactive protein (an inflammatory marker) in an individual’s blood. If the researcher wants a margin of error for the level of C-reactive protein to be less than or equal to 1.5 mg/d and if the standard deviation for C-reactive protein concentrations among arthritis patients was previously documented at 6 mg/dL, how many patients should be recruited for each group of individuals in the study, assuming a 95% confidence interval will be used to quantify the mean differences between the control group and the treatment group?
Recently there have been concerns about the effects of phthalates on the devel- opment of the male reproductive system. Phthalates are common ingredients in many plastics. In a pilot study a researcher gave pregnant rats daily doses of 750 mg/kg of body weight of DEHP (di-2-ethylhexyl phthalate) throughout the period when their pups’ sexual organs were developing. The newly born male rat pups were sacrificed and their seminal vesicles were dissected and weighed. Below are the weights for the eight males (in mg). 1710 1630 1580 1670 1350 1650 1600 1650 If untreated newborn males have a mean of 1700 mg, can you say that rats exposed to DHEP in utero have a significantly lower weight?
Normal and special cause variation are managed very differently. How would you know which type you are responding to without the process limits?
Your company manufactures plastic wrap for food storage. The tear resistance of the wrap, denoted by X, must be controlled so that the wrap can be torn off the roll without too much effort but it does not tear too easily when in use. In a series of tests (see data table below), 15 rolls of wrap are made under carefully controlled conditions and the tear resistance of each rool is measured. The results are used as the basis of a quality assurance specification. If X for a subsequently produced roll falls more than two standard deviations away from the test period average, the process is declared out of specification and production is suspended for routine maintenance. Roll 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 X 134 131 129 133 135 131 134 130 131 136 129 130 133 130 133 a)What is the mean tear resistance?

The specification for the pull strength of a wire that connects an integrated circuit to its frame is 10 g or more. Units made with aluminum wire have a defect rate of 10%. A redesigned manufacturing process, involving the use of gold wire, is being investigated. The goal is to reduce the rate of defects to 5% or less. Out of the first 100 units manufactured with gold wire, only 4 are defective. True or false: a) Since only 4% of the 100 units were defective, we can conclude that the goal has been reached. b) Although the sample percentage is under 5%, this may represent sampling variation, so the goal may not yet be reached. c) There is no use in testing the new process, because no matter what the result is, it could just be due to sampling variation. d) If we sample a large enough number of units, and if the percentage of defective units is far enough below 5%, then it is reasonable to conclude that the goal has been reached.
A clinical trial is being conducted in order to determine the efficacy of a new drug that will be used to treat Crohn’s disease. The efficacy of the medication will not only be determined by the physical improvement of symptoms but will also be determined by using a blood test to examine the concentration C-reactive protein (an inflammatory marker) in an individual’s blood. If the researcher wants a margin of error for the level of C-reactive protein to be less than or equal to 2.9 mg/dL and the standard deviation for C-reactive protein concentrations among Crohn’s disease patients was previously documented at 10.1 mg/dL, how many patients should be recruited for each group of individuals in the study, assuming a 95% confidence interval will be used to quantify the mean differences between the control group and the treatment group?
