For the following information, determine whether a normal sampling distribution can be used, where \( p \) is the population proportion, \( \alpha \) is the level of significance, \( \hat{p} \) is the sample proportion, and \( n \) is the sample size. If it ca be used, test the claim. Claim: \( p \geq 0.47 ; \alpha=0.04 \). Sample statistics: \( \hat{p}=0.40, n=140 \) Let \( q=1-p \) and let \( \hat{q}=1-\hat{p} \). A normal sampling distribution \( \square \) can be used here, since If a normal sampling distribution can be used, identify the hypotheses for testing the claim. Select the correct ch

standard deviation 3 a normal distribution random variable with mean 23 and that the probability \[ P(X>x)=0.66 \]

It is considered appropriate for a researcher to perform the analysis of variance test using a "continuous categorical variable". A) True (B) False

When viewing SPSS output, how does one know what decision to make with regard to the \( H_{0} \) ? (A) Ife confidence level lies between the p-value and \( X^{2} \) obt the \( H_{0} \) can be rejected (B) If \( p a \), the \( H_{0} \) can be rejected (C) If the \( x_{0}^{2} \), the \( H_{0} \) is greater be rejected (D) the critical value, the \( H_{0} \) can be retained

A group of researchers are investigating how different studying strategies impact how much participants remember on a test. They recruit 50 participants and have half of the participants study by just reading a passage over and over for 10 minutes. The other half of the participants spend five minutes reading the passage one time and then answering a series of multiple-choice questions on the material for another five minutes. Finally, the participants write down as many facts from the reading passage as they can in three minutes. Which of the following is the dependent variable of the study? (A) Whether they re-read the passage or tested themselves on the material (D) The number of participants in the study
