A study was carried out to determine the number of women using folic acid supplements in early pregnancy. All women attending a public or private clinic in Ohio were invited to participate and 28 women accepted. Based on previous studies, we know that typically 62% of pregnant women take folic acid supplements during early pregnancy.

a) What is the probability that exactly 25 women take a folic acid supplement during early pregnancy? (Use formula/show work, NOT binompdf or binomcdf.)

b) What is the probability that more than 21 women take folic acid supplements using early pregnancy? (Use binomcdf or binompdf. State function and its arguments.)

c) What is the probability that at least 15, but less than 20 women take folic acid supplements during early pregnancy? (Use binomcdf or binompdf. State function and its arguments.)

A study was carried out to determine whether the resistance of a control circuit in a machine is lower when the machine motor is running. To investigate this question, some of the control circuits were tested as follows. Their resistance was measured while the machine motor was not running and then again while the motor was running for a certain period of time. The values found are listed in ‘Dataset’, with kilo-Ohms as the unit of measurement. Answer the following...

A study was carried out to determine the putting accuracy of golf players on uphill and downhill putts from five feet. In a sample of 100 uphill putts, 90 putts were successful. In a sample of 80 downhill putts, the number of successful putts was 60. Assume α=.05 Is there evidence that the proportion of uphill putts successfully made is larger than downhill putts? Suppose p1=0.95 and p2=0.7. What is the sample size required to have a power of test...

Case Study In Francisco Automotive Manufacturing Plant, a large number of engineering activities are carried out in a wide range of areas. These activities include design, production of parts, assembly, testing, and quality assurance. Many of the manufacturing processes in the plant are performed using automated technologies and equipment. People also perform some of the manufacturing tasks and the plant employs over 400 workers. The decision on whether people or machines will be used for a particular task is dependent...

An experiment is to be carried out to determine the optimal combination of microwave oven settings for microwave popcorn. Cooking time has three possible settings (3,4, and 5 minutes) and cooking power has two settings (low power, high power). The response (to be minimized) is the number of burned plus the number of unpopped kernels. a. Identify the experimental unit. b. Identify the experimental factor(s), levels, and any factor-level combinations if present

It is proposed that a model study be carried out on a proposal low-speed airfoil that is to fly at low altitudes at a speed of 50 m/s. If a 1:10 scale model is to be constructed, what velocity should be used in a wind tunnel? Comment as to the advisability of such a test. Would it be more advisable to perform the test in a 20?C water channel? If a water channel study were undertaken, calculate the drag ratio...
