- Using the 95% significance level, is there a significance difference in stress levels between the three groups?
- Do you reject or accept the null hypothesis?

Step 1

**1.**

There is a significance difference in stress levels between the three groups is obtained below:

**The null and alternative hypothesis is obtained below:**

*Null hypothesis:*

H0: µ1 = µ2 = µ3

That is, there is no significant difference in stress levels between the three groups.

*Alternative hypothesis:*

H1:µ1 ≠ µ2 ≠ µ3

That is, there is significant difference in stress levels between the three groups.

**The p-value for between groups is obtained below:**
