test stätistic. The Genetics & IVF Institute conducted a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of them were boys. Use a 0.01 significance level to test the claim that the YSORT method is effective in increasing the likelihood that a baby will be a boy. Which of the following is the correct test statistic to test this claim? Z-statistic for testing 1 proportion O Z-statistic for testing 2 proportions O Z-statistic for testing 1 mean T-statistic for testing 1 mean O T-statistic for testing 2 means O Chi-square statistic for testing standard deviation

Question
Hypothesis testing, Step 2: Deciding on a test statistic. The Genetics & IVF Institute conducted
a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of
this writing, 291 babies were born to parents using the YSORT method, and 239 of them were
boys. Use a 0.01 significance level to test the claim that the YSORT method is effective in
increasing the likelihood that a baby will be a boy. Which of the following is the correct test
statistic to test this claim?
O Z-statistic for testing 1 proportion
O Z-statistic for testing 2 proportions
O Z-statistic for testing 1 mean
T-statistic for testing 1 mean
T-statistic for testing 2 means
Chi-square statistic for testing standard deviation

Hypothesis testing, Step 1: Stating the competing hypotheses. The Genetics & IVE Institute
conducted a clinical trial of the YSORT method designed to increase the probability of conceiving
a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of
them were boys. Use a 0.01 significance level to test the claim that the YSORT method is
effective in increasing the likelihood that a baby will be a boy. Fill in the blanks below to correctily
state the competing hypotheses here:
Ho:p= [Select]
