What difference between the sample and population results regardless of how well the sampling plan has been designed?

The main difference between sample results and population results is that sample results are less accurate than the population results.

Given nothing and we are required to give the difference between the sample and population results regardless of how well the sampling plan has been designed.

Sample is basically a small part of whole population.

Population is basically includes each unit in the space regarding which the data is to be collected for the research.

The main differences between the sample and population results regardless of how well the sampling plan has been designed are as under:

  1. To collect data of whole population the researcher needs huge money and time whereas in sampling the researcher devotes comparatively less time than data collcection through population.
  2. The data collected through population is more accurate than data collected through sample because sample is just a representation of population and there may happen that there are units different from the sample in the population.

Hence the main difference between sample results and population results is sample results are less accurate than the population results.

if theta is in the first quadrant sin left parenthesis t h e t a right parenthesis equals 0.17 then what is tan left parenthesis
Kazeer [188]

The value of tan\theta in the first quadrant is approximately 0.173.

There are 4 quadrants inside the cartesian aircraft. All trigonometric ratios of sin, cos, tan are high quality inside the first quadrant.in the 2nd quadrant simplest sin is advantageous rest are negative.  within the 1/3 quadrant simplest tan is wonderful inside the fourth quadrant best cos is fantastic.

Given sin \theta=0.17 and \theta is in the first quadrant.

We know from trigonometrical identities that

sin^2\theta+cos^2\theta=1

Substituting the value of  sin \theta in the above equation we get:

or, (0.17)^2+cos^2\theta=1\\or,cos^2\theta=1-0.0289\\or.cos\theta=\pm\sqrt{0.9711}\\or,cos\theta=\pm 0.98544...

As \theta lies in the first quadrant then the value of cos\theta is positive.

∴cos\theta\approx0.98544

From the properties of trigonometry we know that :

tan\theta=\frac{sin\theta}{cos\theta}

or,tan\theta=\frac{0.17}{0.98544} \\or,tan\theta=0.17251\\or,tan\theta\approx0.173

The value of tan\theta is approximately 0.173 to the nearest thousandth . The value is positive as the angle lies in the first quadrant.
