In your work groups, complete the following T/F questions and post as a group:
1. The sample mean x is a reliable point estimate of the population mean μ.
2. We can always estimate a population parameter using sample statistics, regardless of the
sample size or the type of population distribution.
3. The sample size is considered large when it reaches 100.
4. The degrees of freedom are equal to the sample size if the sample size is small.
5. A t-distribution is used when random variable is normally distributed and sample size is less
than 30.
6. The larger the sample size (n ≥ 30), the more skewed is the t-distribution.

2. f if using t-distribution for lower than 30, or using standard normal distribution for larger than 30. If use t-distribution for a number larger than 30 it doesn’t work.

T, but so is 30
