Answer #1
  • The higher the statistical significance the lower the probability of error

True

Higher values of α make it easier to reject the null hypothesis, so choosing higher values for α can reduce the probability of a Type II error.

  • The degrees of freedom in a chi square test are determined based on sample size n

    false

because,  The degrees of freedom for the chi-square are calculated using the following formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns

Determine if the statements below are true or false: The chi-square distribution, just like the normal distribution, has two parameters, mean and standard deviation. The chi-square distribution is always right skewed, regardless of the value of the degrees of freedom parameter. The chi-square statistic is always positive. As the degrees of freedom increases, the shape of the chi-square distribution becomes more skewed. "If you found χ2 = 10 with df = 5, you would fail to reject the Null hypothesis...

True or False: The higher the level of significance of a hypothesis test, the stronger the evidence we require to reject the null hypothesis. True or False: The purpose of a hypothesis test is to assess the evidence in favour of the null hypothesis. True or False: The higher the p-value of a hypothesis test, the more evidence we have to reject the null hypothesis.
