Lillie conducts a hypothesis test and calculates that her sample results have a p-value of 0043, what decision can be made about the null hypothesis? O fail to reject the null O Reject the null

In a survey, each participant indicated how much they agreed with the statement, "Hard work is the way to get what you want in life." Which of the following would you expect to have zero correlation, or close to zero correlation, with the response to the above statement? A) Agreement with the statement, "Happiness mostly depends on luck."   B) Conscientiousness score on a personality inventory test.   C) High school GPA.   D) A random number between 0 and 10, chosen by the participant.

Ramos has a spinning wheel. The Spining wheel has 18 blue numbers 18 white numbers and 2 yellow numbers the table provided shows the frequency with which the ball landed on each color in 200 trials. color blue frequency 18 white frequency 18 yellow frequency 2 . At the 5% significance level do the data suggest that the wheel is out of balance?you will  need to compute the expected counts  to do your calculations remember that the expected counts can be computed with the formula E = np, where n is the number of trials and P is the probability of each color.

Kelly performs a hypothesis test and calculates a p-value of .489 for her sample data. What decision can be made about the null hypothesis? O fail to reject the null O reject the null
