Answer: there are 24 girls.

Step-by-step explanation:

Let x represent the number of boys in fifth grade at lenape elemantary school.

In fifth grade at lenape elemantary school,there are 4/7 as many girls as there are boys. This means that the number of girls in the school would be

4/7 × x = 4x/7

There are 66 students in fifth grade. This means that

x + 4x/7 = 66

Cross multiplying by 7, it becomes

7x + 4x = 462

11x = 462

x = 462/11

x = 42

The number of girls would be

66 - 42 = 24

<h3>What is statistical inference?</h3>

statistical inference uses sample data to make estimates of or draw conclusions about one or more characteristics of a population.

The purpose of statistical inference is to estimate this sample to sample variation or uncertainty. Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. It allows us to provide a plausible range of values for the true value of something in the population, such as the mean, or size of an effect, and it allows us to make statements about whether our study provides evidence to reject a hypothesis.

We have four ideas for using the statistical inference.

1. Estimating uncertainty.

2. Confidence intervals.

3. Hypothesis tests.

4. Connections with other material.
