What is the IQR of <br>15,19,20,25,25,28,29,30,30,35,37,43<br>

Answer:
IQR = 10.
Step-by-step explanation:
15,19,20,25,25,28,29,30,30,35,37,43
There are 12 numbers in the list so the median is the mean of 28 and 29,
The lower quartile is the mean of the 3rd and 4th numbers and the upper quartile is the mean of the 9th and 10th numbers.
Lower quartile = (20+25) / 2 = 22.5.
Upper quartile = (30 + 35) / 2 = 32.5.
So the IQR = 32.5 - 22.5 = 10.
We conclude the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.
- A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
- The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
- If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.

(3.1)(0.02)=0.062
Hey there :)
We know the volume formula of a triangular prism
Volume = base area × height of prism
We are given:
Base of triangle = 5 ft
Height of triangle = 3 ft
Height of prism = 7.5 ft
Apply the formula
V =
( 5 )( 3 ) × 7.5
= 7.5 × 7.5
= 56.24 ft³
