I need help with the following statistical lab. Specifically, how to input and interpret the information and answer the questions that are in bold below. Thank you in advance for your help!

Lab: Crossing the Road

In an observation of a busy thoroughfare pedestrian crossing, 110 people were observed crossing the road. Some pedestrians crossed the road when the "green man" indicated they should, but some crossed when the "red man" warned them not to. Observers grouped pedestrians based on their apparent age. Their observations are summarized in the table below.

Young Adults

Middle Aged

Based on the observed data, could one conclude that crossing the road behavior is independent of age group?

Case Study 2: Hypothesizing if Walk Choices Vary by Age

Use a computer program such as Excel or an online calculator to conduct the statistical test at alpha .05 using the chi-square statistic with the p-value approach.

There is an online chi-square calculator free for use. It will accommodate up to a 5 x 5 contingency table.

There is a Guide to Reporting Chi-Square Test Results in APA Style also free for use.

1. State the hypotheses and summarize the results and conclusions:

2. State the hypotheses in complete statements and statistical symbols.

3. Report the value of the test statistic and degrees of freedom.

4. Report the p-value of the test statistic.

5. Report whether the result is statistically significant.

6. State the conclusion in APA style.

7. Paste in a copy or screenshot of the calculator output. No credit will be given without this.
