Choose the correct definition of significance level from the list below. A significance level is Option 1 and 5 are WRONG Choose the correct definition of significance level from the list below A significance level is the probability of failing to reject the null hypothesis when the alternative hypothesis is true. the minimum acceptable chance of making a type I error. O the probability that an event occurred as a result of a causative factor rather than by chance. the...
A 0.05 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5. Assume that sample data consists of 78 girls in 169 births, so the sample statistic of results in a z score that is 1 standard deviation below 0. Complete parts (a) through (h) below.

Suppose that three hypothesis tests are carried out, each using significance level 0.05. What is the worst-case probability of a type I error in at least one of these tests? 0.05 0.15 0.3 1
A 0.05 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is different from 0.5. a. Identify the null hypothesis and the alternative hypothesis. Choose the correct answer below. A. Upper H 0H0 : pnot equals≠0.5 Upper H 1H1 : pequals=0.5 B. Upper H 0H0 : pequals=0.5 Upper H 1H1 : pgreater than>0.5 C. Upper H 0H0 : pequals=0.5 Upper H 1H1 :...
Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.

Which statement best describes the significance level of a hypothesis test? The probability of obtaining a sample under the assumption that the null hypothesis is true that is more unusual than the observed sample b. The probability of making a Type 1 error The probability of making a Type Il error. d. The probability of correctly rejecting the null hypothesis.
In a t-test Luke decided to use a two tailed alpha=0.05. If, the null hypothesis is true, what is the probability of making a type I Error? 0.1 0.05 0.95 not enough information
(3 points) When one changes the significance level of a hypothesis test from 0.10 to 0.05, which of the following will happen? Check all that apply. A. The chance of committing a Type I error changes from 0.10 to 0.05. B. The test becomes more stringent to reject the null hypothesis (i.e., it becomes harder to reject the null hypothesis). C. The chance that the null hypothesis is true changes from 0.10 to 0.05. D. It becomes easier to prove...
A significance level for a hypothesis test is given as . Interpret this value. The probability of making a Type II error is .99. The smallest value of α that you can use and still reject H0 is .01. There is a 1% chance that the sample will be biased. The probability of making a Type I error is .01.
