If H0:, which one of the following statements is correct?
Type l error: decide not to reject u<=100 when u is really <=100
Type l error: decide not to reject u<=100 when u is not <=100
Type Il error: decide not to reject u<= 100 when u is really <= 100
Type Il error: decide not to reject u<=100 when u is not<= 100
Use the chart below to answer Questions 16 through 33.
The study looks at what affects wage (wage, in dollars). The two factors being examined are years of education (X1=education, in years) and previous work experience (X2=Yes/No).

middle parts were wrong. Please explain
Again consider the automobile parts supplier situation. Remember that a problem-solving team will be assigned to rectify the process producing the cylindrical engine parts if the null hypothesis Ho: u= 3 is rejected in favor of Ha: u#3. In this exercise we calculate probabilities of various Type Il errors in the context of this situation. (a) Suppose that the parts supplier's...
I need help with questions a through g. could we use t
alpha instead of z? since we are talking about a sample mean ?
please show z & t, is it indistinct to use either or ?
ne expected mean of a normal population is 100, and its standard deviation is 12. Asample of 36 measurements gives a sample mean of 96, using the α,01 tevel of significance a test is to be made to decide between "population mean...

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing your score for this subsection, you're interested in the mean score l among the general population on this subsection. The website reports that u is 145, but you believe that u is greater than 145. To do a statistical test, you choose a random sample of 100 people and have them take the personality...
1 A researcher wants to find out which type of classroom instruction significantly improves students’ test performance. He designed four types of instruction for four samples of students. Later all four samples were given the same test and their average performance was compared. What statistical test should be used by the researcher to analyze the results of this study? A. Pearson correlation B. t-test for independent groups C. one-factor Anova for between groups D. Chi2 for Independence 2 A researcher...
We're interested in the amount of time spent at work by college graduates employed full-time. The standard amount of time spent at work by full-time employees is 40 hours per week. We suspect that the mean number μ of hours worked per week by college graduates is more than 40 hours and wish to do a statistical test. We select a random sample of 100 college graduates employed full-time and compute the mean number of hours worked per week by...
Answers to the following questions should be calculated in Matlab and given to 4 decimal places. Be careful not to introduce errors by rounding in any intermediate calculations as this may lead to an incorrect final answer. A confidence interval is desired for the true average load loss u (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. A random sample of 49 motors were tested...
Use the following regression output from R studio and answer the
following questions.
1. Comment on the relation between the two test marks.
A. There appears to be no linear relation between the
two test marks
B. There appears to be strong negative linear relation between the
two test marks.
C. There appears to be weak positive linear relation between the
two test marks.
D. There appears to be strong positive linear relation
between the two test marks.
2. If the linear...
