Jimmy’s family moved to a tropical climate. For the year that followed, he recorded the number of days that had a temperature ab

ove 40 degrees C each month. His data contained -
14, 14, 10, 12, 11, 13, 11, 11, 14, 10, 13 and 8

1) Find the mean for his data set of days that had a temperature above 40 degrees C.

2) Find the median for his data set of days that had a temperature above 40 degrees C.

3) Find the mode for his data set of days that had a temperature above 40 degrees C.

4) If, instead, there are 5 more days per month that had a temperature above 40 degrees C, what will be the mean for the data?

5) If, instead, there are 2 more days per month that had a temperature above 40 degrees C, what will be the mode for the data?

6) If the number of days per month that had a temperature above 40 degrees C, doubles each month in that year, what will be the median for the data?

7) For what value of x will 9, 16, and x have the same mean (average) as that of 26 and 12?

8) For what value of x will 55 and x have the mean (average) as 67?

9) The mean (average) weight of three boys is 40 pounds. One of the boys weighs 50 pounds. The other two boys have the same weight. Find the weight of each of the boys?

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u>:</u></em></h2><h2>\frac{1}{5}</h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

Number of numbers of each side of the cube

= 4, 5, 6, 7, 8 and 9

= 6 numbers

Number of sides of cube having the number 5

= 1

<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>

Probability of getting a side of the cube of no. 5 is

=  \frac{no. \: of \: favourable \: outcomes}{total \: no. \: of \: possible \: outcomes}

=  \frac{1}{6} (ans) \: (option \: B)

MA_775_DIABLO [31]

Answer:

Mean is the measure of central tendency is most appropriate to describe the given data.

Step-by-step explanation:

We are given the following in the question:

The distribution of time in seconds is a bell shaped distribution that is a normal distribution.

Properties of a normal distribution:

  • The mean, mode and median for a normal distribution are equal.
  • The mean divides the data into two equal parts.
  • The area under the graph is 1.
  • Thus, mean is the most appropriate measure of central tendency for normally distributed data.

Thus, the correct answer is

Mean is the measure of central tendency is most appropriate to describe the given data.
