Spacers are manufactured to the mean dimension and tolerance shown in Figure 29-12. An inspector measures 10 spacers and records the following thicknesses: 0.372" 0.376" 0.379" 0.375" 0.370" 0.373" 0.377" 0.378" 0.371" 0.380" Which spacers are defective (above the maximum limit or below the minimum limit)? All dimensions are in inches.
The mean arterial pressure (or MAP, average arterial pressure in one cardiac cycle) is a measure for perfusion status. You are interested to know if it is possible to predict an adult's MAP (Y) based on the body surface area (X). Suppose you randomly selected 50 adults, and measured their mean arterial blood pressure (in mmHg) & body surface area (in m2). The results are reflected below: I = 1.6 s, = 0.5 y = 80.1 s, = 16.9 r 0.8 %3D %3D (Source: Nall, R. (2018, April 10). Mean arterial pressure: Normal, low, high readings plus treatment.

1.56 Longleaf pine trees. The Wade Tract in Thomas County, Georgia, is an old-growth forest of longleaf pine trees (Pinus palustris) that has survived in a relatively undisturbed state since before the settlement of the area by Europeans. A study collected data on 584 of these trees. One of the variables measured was the diameter at breast height (DBH). This is the diameter of the tree at 4.5 feet, and the units are centimeters (cm). Only trees with DBH greater than 1.5 cm were sampled. Here are the diameters of a random sample of 40 of these trees: PINES 27 10.5 13.3 26.0 18.3 52.2 9.2 26.1 17.6 40.5 31.8 47.2 11.4 2.7 69.3 44.4 16.9 35.7 5.4 44.2 2.2 4.3 7.8 38.1 2.2 11.4 51.5 4.9 39.7 32.6 51.8 43.6 2.3 44.6 31.5 40.3 22.3 43.3 37.5 29.1 27.9 (a) Find the five-number summary for these data. (b) Make a boxplot. (c) Make a histogram. (d) Write a short summary of the major features of this distribution. Do you prefer the boxplot or the histogram for these data?
The "spring-like effect" in a golf club could be determined by measuring the coefficient of restitution (the ratio of the outbound velocity to the inbound velocity of a golf ball fired at the clubhead). Twelve randomly selected drivers produced by two clubmakers are tested and the coefficient of restitution measured. The data follow: Club 1: 0.8406, 0.8104, 0.8234, 0.8198, 0.8235, 0.8562, 0.8123, 0.7976, 0.8184, 0.8265, 0.7773, 0.7871 Club 2: 0.8305, 0.7905, 0.8352, 0.8380, 0.8145, 0.8465, 0.8244, 0.8014, 0.8309, 0.8405, 0.8256, 0.8476 Test the hypothesis that both brands of ball have equal mean overall distance. Use α = 0.05 and assume equal variances. Question: Reject H0 if t0 < ___ or if t0 > ___.
The calcium (Ca) content of a powdered mineral substance was analyzed 10 times with the following percent compositions recorded:.0271 .0282 .0279 .0281 .0268.0271 .0281 .0269 .0275 .0276a. Draw a dotplot to describe the data. (HINT: The scale of the horizontal axis should range from .0260 to .0290.)b. Draw a stem and leaf plot for the data. Use the numbers in the hundredths and thousandths places as the stem.c. Are any of the measurements inconsistent with the other measurements, indicating that the technician may have made an error in the analysis?
in uncam dIfferent from the mean amount of airborne bacteria in uncarpeted rooms. To test this, carpeted and ount of bacteria on the dish was recorded The results are presented in the following table: Uncarpeted rooms Carpeted rooms 12.1 9.8 Sample mean of bacteria per ft' Sample std. dev. of bacteria per ft Number of rooms tested 3.2 2.7 23 %3D U.05 to see test if the amount off airborne bacteria is different in carpeted rooms than in uncarpeted rooms. I. State your hypotheses II. State the allowable type I error rate (a.) III. Calculate your test statistic, the p-value and draw the physical representation of the p-value IV. Make your decision to either reject the null or fail to reject the null. V. Make a concluding statement. b.) Run a 95% confidence interval for the hypothesis test above. Don't forget to make a proper conclusion.
