Due in 3 hours, 31 minutes. Due Mon 01/06/2020 11:59 pm An experiment was conducted to measure the effectiveness of various feed supplements on the growth rate of chickens A five number summary of the weights of the chicks in grams six weeks after hatching is as follows. Source: Anonymous (1948) Biometrika, 35, 214. • Min = 110 • Q1 = 200 • Median = 245 • Q3 = 329 • Max-410 1. About 2. About 3. About 4. About percent of the chicks weigh more than 200 percent of the chicks weigh more than 245 percent of the chicks weigh more than 329. percent of the chicks weigh between 200 and 329 Points possible: 4 Untimited attempts.

Answer 1

Solution:

First quarile (Q₁) can be interpreted as follows:

The first quatile devides the whole data set such that, about 75% of the observations will be more than the Q₁ value and 25% of the observations will be less than Q₁ value.

Median can be interpreted as follows:

The median value devides the whole data set in two equal parts. It means 50% of the observations will be more than the median value and 50% of the observations will be less than median value.

Third quartile (Q₃) can be interpreted as follows:

The third quatile devides the whole data set such that, about 25% of the observations will be more than the Q₃ value and 75% of the observations will be less than Q₃ value.

We are given, Q₁ = 200, median = 245 and Q₃ = 329.

1) About 75 percent of the chicks weigh more than 200.

2) About 50 percent of the chicks weigh more than 245.

3) About 25 percent of the chicks weigh more than 329.

4) About 50 percent of the chicks weighs between 200 and 329.
