Use the following information to solve the problem. BA force of gravity, BA = weight of the box = 23° 23° AC magnitude of the force needed to pull the box up the ramp BC magnitude of the force of the box against the ramp If the box weighs 110 pounds, find the magnitude of the force needed to pull it up the ramp. 6 The magnitude of the force needed to pull the box up the ramp is approximately pounds.

You conducted a Chi-Square Goodness of Fit Test in your ASCI 691 capstone project. Unfortunately, you did not get the sample size you had hoped for during your research. You were able to get 55 in the sample. Calculate your actual power (post hoc). You did a 2 X 2 table. Assume you had a medium effect size.

A textile engineer is interested in measuring heat resistance of four different types of treads used in making fire-resistant clothing for firefighters. A random sample of 20 threads from each type was taken and subjected to a heat test to determine resistance (the length of time the fibers survive before starting to burn).    a) Explain what type of study this is and why.

Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude). This year's results were: Aptitude Score012345Frequency1344414 The mean (¯xx¯) aptitude score: (Please show your answer to 1 decimal place.) The median aptitude score: The mode aptitude score: (Please separate your answers by ',' in bimodal situation. Enter DNE if there is no mode.)

Using the chi-square test table to answer this question. Proper working out and right answers required.

Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Patients experiencing symptoms of a heart attack are routinely transported to a hospital in an ambulance. In a study of a new treatment thought to reduce damage to the heart, patients experiencing symptoms of a heart attack were randomly assigned to one of two groups. During transportation to the hospital, patients in one group received standard care, and patients in the other group received the new treatment consisting of standard care and the application of a blood pressure cuff. The response variable measured for each patient was a number between 0 and 1, referred to as the myocardial salvage index (MSI). A higher MSI value indicates a more positive outcome for the patient. Summary statistics for the MSI responses of the two groups are shown in the table below. Do the data provide…
