- Types of error and data bias 3. For each set of hypotheses, describe the Type I and Type II error and decide which type of error would be more consequential from an environmental standpoint (you may want to think about consequential in terms of 'cost). a. Ho: The water is not contaminated Ha: The water is contaminated You conclude that the water is contaminated when in reality it is not contaminated. You conclude that the water is not contaminated when in reality it is contaminated. Type I Error: Type II Error: You conclude that the water is contaminated when in reality it is not contaminated. You conclude that the water is not contaminated when in reality it is contaminated. A Type I Type II error would be more serious because... Explanation: b.

- Suppose you conduct a hypothesis test to determine whether or not the average age difference between married couples is less than 5 years. You conduct this test at the 0.10 significance level and come to the conclusion that 0.01 < p-value < 0.02. What is the correct decision?

- screenshotIf the variability between the different sample means taken from the same population is small, we can therefore conclude that: O The estimate of the parameter mean is lesser O The estimate of the parameter mean is higher O The estimate of the parameter mean is equal O The estimate of the parameter mean is more accurateAssume you are conducting a hypothesis test to determine if pesticides cause cancer in rural areas. The hypotheses are: The null hypothesis is no cancer. The alternate hypothesis is cancer. Select if the result for Box Cis correct, a Type l error., a Type Il error or if there is insufficient information to make the decision. *****Read the labels very carefully Ho: no cancer Hicancer Reality: Reality: Null is true |(he. no cancer) Alternate is true (L.e. cancer) Decision: Accept the null hypothesis (Le. test is negative for cancer) A B Decision: Reject the null hypothesis (Le. test is positive for cancer) C D O Correct O Type l error O Type Il error O There is insufficient evidence.
