QuestionConjecture the percentage of the population with type O blood from a sample result of 0.42. Is it descriptive or inferential statistics?

Studdy Solution

STEP 1

Assumptions1. The sample result of0.42 represents the proportion of the sample that has type O blood. . The sample is representative of the population.
3. We are assuming that the sample result can be used to estimate the percentage of the population with type O blood.

STEP 2

First, we need to convert the sample result to a percentage. We can do this by multiplying the sample result by100.
Percentage=Sample resulttimes100Percentage = Sample\, result \\times100

STEP 3

Now, plug in the given value for the sample result to calculate the percentage.
Percentage=0.42times100Percentage =0.42 \\times100

STEP 4

Calculate the percentage.
Percentage=0.42times100=42%Percentage =0.42 \\times100 =42\%

STEP 5

Now that we have the percentage, we can conjecture that42% of the population has type O blood. This is based on the assumption that the sample is representative of the population.

STEP 6

This is an example of inferential statistics. Inferential statistics uses data from a sample to make inferences about a population. In this case, we are using the sample result to make an inference about the percentage of the population that has type O blood.
The conjectured percentage of the population that has type O blood is42%. This is an example of inferential statistics.
