Find the mean, median, mode, and range for each of the following sets of numbers
Sidana [21]

Answer:

The mean - 45\dfrac{2}{7}; the median - 35, the mode - 27, the range - 47.

Step-by-step explanation:

Arrange the set of data (31,74,27,58,65,27,35) in ascending order:

27, 27, 31, 35, 58, 65, 74.

The mean is the usual average, so add aal numbers and then divide by the number of numbers:

\dfrac{27+27+31+35+58+65+74}{7}=\dfrac{317}{7}=45\dfrac{2}{7}.

The median is the middle value. The middle value in the row 27, 27, 31, 35, 58, 65, 74 is 35.

The mode is the number that is repeated more often than any other, so 27 is the mode.

The largest value in the set is 74, and the smallest is 27, so the range is 74 – 27 = 47.

LenaWriter [7]

The sample must be random and independently selected from the normally distributed population.

n*p and n*q both must be greater than 5

There must be two outcomes "success" and "failure"

The number of trials must be fixed.

From the given information 2), 3)and 4) conditions are satisfied, but not 1) because we are not given that people are selected randomly.

Answer: The sample observations are not a random​sample, so a test about a population proportion using the normal approximating method cannot be used.
