Answer 1

The other answer for USA TP is 26.25

Explanation:

The mean is the average of the numbers.

29.8 + 29.6 + 28.9 + 27.1 + 26.4 + 25.5 + 24.5 + 24.0 + 23.8 + 22.9

10

= 26.25

Answer 2

To calculate the interquartile range of a dataset, we first arrange the dataset in order:

Since the given dataset is already arranged in order.

We obtain the Q1 and the Q3 data values.

The Q1 value is the value for which 25% of the datavalues lie below it. For the given dataset, the Q1 value is 24.

Similarly, the Q3 value is the value for which 25% of the datavalues lie above it. For the given dataset, the Q1 value is 28.9.

The interquartile range is given by

IQR = Q3 - Q1 = 28.9 - 24 = 4.9

Therefore, the interquartile range (IQR) of the data set is 4.9.
