Answer:

We know the following information:

Alan is conducting an experiment to determine whether a new medication is effective in reducing coughing.

Alan finds 2000 volunteers with coughing issues and divides them into two groups.

The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of coughing.

Therefore, Alan can conclude that the new medication is effective in reducing coughing.

Alan can say that the medicine given to people most likely worked as the treatment group showed signs of reduced coughing.

Given the length of three sides of a triangle, which is a right triangle?
RSB [31]

The aides of a right triangle will always satisfy the Pythagorean relationship ...

                   a² + b²=  c²

We can take each of these and try it out:

(1) ... 10² + 24² = 100 + 576  = 676
         √676 = <em>26  Yes</em>.

(2) ... 12² + 18²  =  144 + 324  =  468
           √468  =  21.6, not 20.  <em>No.</em>

(3) ... 15² + 26²  =  225 + 676  =  901
         √901  =  30.017  Awfully close.  As an engineer, I'll buy this one. <em>Yes.</em>

(4) ...  40² + 50²  =  1,600 + 2,500  =  4,100
          √4,100  =  64.03, not 80.<em>  No.</em>

(g) A company’s tax identification.  Nominal

(h) The Standard & Poor’s bond ratings of cities Ordinal

Step-by-step explanation:

Nominal, ordinal, interval, or ratio data are the four fundamental levels of measurement scales that are used to capture data.

Nominal scales are used for labeling variables, without any quantitative value.

Ordinal the order of the values is what is significant, but the differences between each one is not really known.

Interval we know both, the order and the exact differences between the values

Ratio data they have the order, the exact value between units, and have an absolute zero

Approximately 54% of mathematics students do their homework on time. In a class of 250 students, what is the mean, variance, and
sleet_krkn [62]

Answer:

A) Mean = 135 Variance = 62 Standard Deviation = 8

Step-by-step explanation:

Given that :

Proportion (p) = 54%

Sample size (n) = 250

Using Normal approximation :

Mean = np

Mean = 250 * 0.54 = 135

Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46

Variance = (250 * 0.54 * 0.46) = 62.1 = 62

Standard deviation = √variance = √62.1

Standard deviation = 7.8803553 = 8
