Verified
If you were constructing a 99% confidence interval of the population mean based on a sample of n = 25 where the standard deviation of the sample s = 0.05, the critical value of t will be:
A) 2.7969
B) 2.7874
C) 2.4922
D) 2.4851
E) 2.3562
Confidence Interval
A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter, given a specified level of confidence.
Critical Value
A point on the scale of the test statistic beyond which we reject the null hypothesis.
Standard Deviation
An indicator that evaluates how much the data in a set diverges or spreads out in comparison to the average value, showing the extent of distribution of the observations.
- Undertake the application of degrees of freedom in t-distribution calculations.
- Assess critical values and designate rejection zones within the framework of hypothesis testing by means of the t-distribution.
