-1\le\sin\theta\le1\implies(\csc\theta\le-1)\cup(\csc\theta\ge1)

which means \csc\theta=0 has no solution, and we can omit that factor.

This leaves us with

2\cos\theta-1=0\implies\cos\theta=\dfrac12

which occurs for \theta=\pm\dfrac\pi3+2n\pi.

14) the slope for the first problem is -2/8.
Not proportional

15) The slope is 1/6.
Not proportional

16) The slope is 0.
Not proportional

To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0).

Hope this helps! Merry Christmas!✨❤️

A doctor is measuring the mean systolic blood pressure of female students at a large college. Systolic blood pressure is known t
Nana76 [90]

Answer:

The correct option is (b).

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for population mean (<em>μ</em>) is:

CI=\bar x\pm z_{\alpha/2}\times\frac{SD}{\sqrt{n}}

The confidence interval for population mean can be computed using either the <em>z</em>-interval or <em>t</em>-interval.

The <em>t</em>-interval is used if the following conditions are satisfied:

  • The population standard deviation is not known
  • The sample size is large enough
  • The population from which the sample is selected is normally distributed.

For computing a (1 - <em>α</em>)% confidence interval for population mean , it is necessary for the population to normally distributed if the sample selected is small, i.e.<em>n</em> < 30, because only then the sampling distribution of sample mean will be approximated by the normal distribution.

In this case the sample size is, <em>n</em> = 28 < 30.

Also it is provided that the systolic blood pressure is known to have a skewed distribution.

Since the sample is small and the population is not normally distributed, the  sampling distribution of sample mean will not be approximated by the normal distribution.

Thus, no conclusion can be drawn from the 90% confidence interval for the mean systolic blood pressure.

The correct option is (b).
