The overall average score on a test of Emotional Intelligence is 50 for the general population.  A member of the admissions committee for the Ph.D. program in clinical psychology at OU wants to know whether applicants to the program are higher in Emotional Intelligence than the general population.  Twenty-five applicants were randomly selected from the applicant pool and were given the Emotional Intelligence test.  The applicants’ mean score was 60 with a standard deviation of 10.  Use an alpha level equal to 0.01 to determine whether the applicants scored higher on the Emotional Intelligence test.

a. Write the null and alternative hypotheses in words.                                   (2 points)

Q8: Null in Words

Q9: Alternative in Words

b. Write the null and alternative hypotheses in symbols.                               (1 point)

Q10: Both null and alternative in symbols

Answer #1

Null hypothesis in words: The overall average score on the test of Emotional Intelligence is equal to 50 for the general population.

Alternative hypothesis in words: The overall average score on the test of Emotional Intelligence is greater than 50 for the general population.

Null hypothesis in symbol, H0: μ = 50

Alternative hypothesis in symbol, H1: μ > 50

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of 300. On the basis of these data, can the researcher conclude that the preparation course...

In the population, IQ scores are normally distributed with a mean of 100. A charter school wants to know if their students have an IQ that is higher than the population mean. They take a random sample of 15 students and find that they have a mean IQ of 109 with a sample standard deviation of 20. Test at 1% significance level whether the average IQ score in this school is higher than the population mean. a) Write down null...

1) The value of the z-score that is obtained for a hypothesis test is influenced by several factors. Some factors influence the size of the numerator of the z-score and other factors influence the size of the standard error in the denominator. For each of the following, indicate whether the factor influences the numerator or denominator of the z-score and determine whether the effect would be to increase the value of z (farther from zero) or decrease the value of...

A political scientist hypothesizes that a political ad will reduce attitudes about a particular issue. The scientist randomly asks 31 individuals walking by to see the ad and then take a quiz on the issue. The general public that knows little to nothing about the issue, on average, scores 50 on the quiz. The individuals that saw the ad scored an average of 53.59 with a variance of 25.70. What can the political scientist conclude with an α of 0.05?...
