A statement that the independent variable had no effect is called the alternative hypothesis. True False

A population of values has a normal distribution with \( \mu=111.2 \) and \( \sigma=39 \). You intend to draw a random sample of size \( n=231 \). Please show your answers as numbers accurate to 4 decimal places. Find the probability that a single randomly selected value is between 109.1 and 116.8 . \( P(109.1<X<116.8)=\square \)

24. What is the \( y \)-intercept of the trend line equation, and what does it mean in the context of the situation?

The following data are the estimated market values (in millions of dollars) of 12 companies in the auto part business: \( 22,20,15,16,38,11,13,10,19,26,17,30 \) Round your answers in part (a) to 1 decimal place. (a) Calculate the values of \( Q_{1}, Q_{2}, Q_{3} \) \( Q_{1}=\square \) \( Q_{2}= \) \( Q_{3}= \)

\( \alpha \) (alpha) is also known as the probability of failing to reject the \( H_{0} \) when it is false. True False
