Step-by-step explanation:
1. Null and alternative hypothesis
2. Significance level
Freedom degrees is given by:
For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:
3. Test statistic
In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if
Conclusion:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
