Concept explainers
After viewing the results of her computer experiments, it slowly dawns on the hydrologist that the “optimal shape” of the container is consistent with what would be expected based on the conceptualization that the water in the ideal container would consist of a collection of small parcels of water of mass

(a) All other factors being equal, is there evidence that men sleep more than women? Test the null hypothesis that men sleep the same amount of time as women against the alternative hypothesis that men sleep more than women at 5% significance level. (b) Is there a statistically significant tradeoff between working and sleeping? What is the estimated tradeoff?arrow_forward
- Conceptual Questions: 1. Suture anchors are used to reattach tendons or ligaments to bone. You are creating an anchor system for the ACL that involves two suture anchors on the distal end of the joint. You plan a study that compares this new anchor system to the currently used anchor system. Based on your experimental study, you have two outcome measures: i) the failure status of the suture during an experimental protocol and ii) the ultimate tensile failure load. Complete the following tasks: A) Would the two experimental groups in Figure lii be considered independent or disjoint? Is the outcome measure in Figure 1i considered independent or disjoint? Provide a brief explanation for each Figure li: Number of Occurrences 10 Figure lii: 40 Failure Load (kN) 30 20 10 5 0 Current anchors Failure ■ No failure Current anchors Experimental anchors Experimental anchorsarrow_forward: 39% in 30m 20 CALENDAR Travel to Home Today at 11:02 PM Green Street f...

The process engineer would like to optimise the strength of the component by optimising the following factors: temperature = 190°C and 210°C, pressure = 50 MPa and 100 MPa, and speed of injection = 10 mm/s and 50 mm/s. What type of mathematical model that the engineer can develop if the relationship is linear and no interactions are significant? Write down the general equation that relates the strength of the component with the process factors.arrow_forward

Produce a linear model for the capacity in the form Pn= C1 X Area + C2 X SR, show the statistics of the linear model on this paper. Use your linear model to predict Pn for the case of Area= 200 and SR = 35. Produce a 95% confidence interval for your expected value of Pn at Area=200mm2 and SR=35. Find the maximum possible Pn and the minimum possible Pn based on 95% confidence limits of the parameters. Suggest how to improve your model by saying which one of the two factors must be treated nonlinearly and show why you think so!

The researchers recruited a sample of 40 female and 40 male heterosexual Caucasian college students from British universities for a study on the attractiveness of body types. Among adults, a body mass index (BMI, in kg/m²) value between 18.5 and 24.9 is considered healthy, but attractiveness may not be solely due to health. Using a 3D computer avatar, the participants constructed what they considered to be the ideal body of an adult of their own gender. Here is the Minitab result for the mean ideal BMI for women (top) and men (bottom):5 One-sample T N=40 Mean=18.850 Stdev= 1.750 SE mean= 0.277 95% CI (18.290, 19.410) One-sample t N=40 Mean= 25.860 Stdev= 3.950 SE mean= 0.625 95% CI (24.597, 27.123) A) Interpret the confidence interval for women in context.
