Step 3

A) Test statistic χ² = 42.6850

B) P(χ² > 42.6850) = 0.0281 (Right tailed)

C) Since p-value > 0.05 hence reject the null hypothesis

There is sufficient evidence to conclude that the standard deviation (variability) has increased this season

D) Critical value , χ²_R = 40.1132

Rejection region , reject H0 if test statistic > 40.1132

Since test statistic is > in the critical region hence we reject the null hypothesis

Chapt 4, Q8: Answer this question please The antibody production of 12 male red-winged blackbirds before and after receiving testosterone implants was compared. The units for antibody levels were natural log (10-3 optical density) per minute (ln(mOD/min)). The mean change in antibody production was d = 0.056, and the standard deviation was sd = 0.240 If you were assigned the task of repeating this experiment, and wanted to ensure that you could detect a mean change of 0.08 units with a probability of 0.8, then what sample size would you use? Since we are calculating n for a study of individuals, answers should be rounded to the closest whole number.
