Alpha false and true Which of the following statements are true? If false, explain briefly.
solmaris [256]

Answer:

A. False

B. True

C. True

D.True

Step-by-step explanation:

A. False . The significance level or alpha is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. 0.01 alpha is better than 0.05 alpha . 0.01 indicate a 1% risk of rejecting the null hypothesis when it is true .

B. True . If the p-value is less than alpha, we reject the null hypothesis . Therefore statistically significant.

C . True . If the p-value is less than alpha, we reject the null hypothesis

D. True . Alpha will be greater than p-value . Therefore we will reject .

A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work
galben [10]
To find the percent of games the soccer team won, you would do 160 multiplied by 0.65, because if you were to convert the 65% into a decimal, you would get 0.65. Notice the key word, "of". This refers to multiplication. So when doing 160*0.65, you get 104 games won. Therefore the soccer team won 104 of their games.

Hope this helps! :D Feel free to ask more questions, or ask me questions about my explanation.
