Expert Solution

Step 1
There are two types of errors a researcher can make while testing a Hypothesis : Type I and Type II error
Type 1 error occurs when we reject a null hypothesis when it is true. Type II error occurs when the null hypothesis is accepted when it is not true.
Let say :
Null Hypothesis : The coins you have in your bag are fair
Alternate : The coins you have in your bag are not fair
Type 1 error is rejecting that The coins you have in your bag are fair when in actual they are
Type II error is accepting that The coins you have in your bag are fair when in actual they are not
Refer to the below given chart of Type 1 and type 2 errors

- Define "alternative hypothesis" & their conditions?arrow_forwardSuppose you wish to find out the answer to the age-old question, "Do people prefer Cola 1 or Cola 2?" You conduct a blind taste test in which individuals are randomly asked to drink one of the colas first, followed by the other cola, and then asked to disclose which drink they prefer. Results of your taste test indicate that 59 of 100 individuals prefer Cola 2. Complete parts a through c. (a) Conduct a hypothesis test (preferably using technology) Ho: p = po versus H₁: ppo for po = 0.48, 0.49, 0.50, 0.68, 0.69, 0.70 at the a= 0.05 level of significance. For which values of po do you not reject the null hypothesis? What do each of the values of po represent? Do not reject the null hypothesis for the values of po between (Type integers or decimals. Do not round.) O and inclusively.arrow_forward1- Type II error occurs when a false null hypothesis is not rejected Select one: True Falsearrow_forward
