The researchers also performed control treatments. Suggest two controls they might have used, and explain how each would be helpful in interpreting the results described

The birth control shot is one of the most effective methods of birth control available, and it works best when you get the shot regularly, every 12 weeks. Under ideal conditions, only 1 % of women taking the shot become pregnant within one year. In typical use, however, 3% become pregnant. 7 Choose at random 20 women using the shot as their method of birth control. We count the number who become pregnant in the next year.

(a) Explain why this is a binomial setting.

(b) What is the probability that at least one of the women becomes pregnant under ideal conditions? What is the probability in typical use?

A __________ is a set of individual controls that are bound to the columns in a single row. a. data-bound control set b. data collection c. Details view d. Column view

Once you have created a PictureBox control, you use its __________ property to specify the image that it will display. a. Image b. Source c. DrawSource d. ImageList

Using Previous Figure, explain how flow control can be achieved at the sender site in TCP (from the sending TCP to the sending application). Draw a representation.

In TCP, some segment types can be used only for control; they cannot be used to carry data at the same time. Can you define some of these segments?

In an inspection with a sample size of $12$ and a sample number of $40$, it was found that the average range was $14$ and the average of averages was $80$. Calculate the control limits for averages and for ranges.

What internal control procedure(s) would provide protection against the following threats?

n. The company’s website is unavailable for seven hours because of a power outage.

A vehicle with a particular defect in its emission control system is taken to a succession of randomly selected mechanics until r = 3 of them have correctly diagnosed the problem. Suppose that this requires diagnoses by 20 different mechanics (so there were 17 incorrect diagnoses). Let p = P(correct diagnosis), so p is the proportion of all mechanics who would correctly diagnose the problem. What is the mle of p? Is it the same as the mle if a random sample of 20 mechanics results in 3 correct diagnoses?

"Just 1 capsule of Brand $X$ can provide 24 hours of acid control." (Actual brand will not be named.) What must be more clearly defined in this statement?

Explain what happens with respect to control and regulation of your salt and water balance when you go to a movie and eat a lot of very salty popcorn.

The competitive equilibrium rent in the city of Lowell is currently $1,000 per month. The government decides to enact rent control and establish a price ceiling of$750 per month for apartments. Briefly explain whether rent control is likely to make each of the following people better or worse off.

A landlord who intends to ignore the law and illegally charge the highest rent possible for his apartments

An electron initially located at the origin of a coordinate system is projected horizontally into a uniform electric field with magnitude $E$ and directed upward. If the initial speed of the electron is $v_0$, then its trajectory is

$$x=v_0t\hspace{6pt}y=-\frac{1}{2}\left(\frac{eE}{m}\right)t^2$$

where $e$ is the charge of the electron and $m$ is its mass. Show that the trajectory of the electron is a parabola.

Note:The deflection of electrons by an electric field is used to control the direction of an electron beam in an electron gun.

To control an agricultural pest called the medfly (Mediterranean fruit fly), $N$ sterilized male flies are released into the general fly population every day. If $s$ is the proportion of these sterilized flies that survive a given day, then $Ns^k$ will survive for $k$ days. If $s=$ 0.9 and 10,000 sterilized males are needed to control the medfly population in a given area, how many should be released every day?
