The p-value for a hypothesis test turns out to be 0.09484. At a 2% level of significance, what is the proper decision? Reject H0H0 Fail to reject H0
Perform the hypothesis tests as required. Use the four-step method. 2. Suppose the annual incidence of asthma in the general population among children 0–4 years of age is 1.4% for boys. If 10 cases are observed over 1 year among 500 boys 0–4 years of age with smoking mothers, then test whether there is a significant difference in asthma incidence between this group and the general population using the critical-value method with a two-sided test.
Two extrusion machines that manufacture steel rods are being compared. In a sample of 1000 rods taken from machine 1, 960 met specifications regarding length and diameter. In a sample of 600 rods taken from machine 2, 582 met the specifications. Machine 2 is more expensive to run, so it is decided that machine 1 will be used unless it can be convincingly shown that machine 2 produces a larger proportion of rods meeting specifications. a) State the appropriate null and alternate hypotheses for making the decision as to which machine to use. b) Compute the P-value. c) Which machine should be used?
A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the critical region are t = ± 2.080, then how many individuals are in the sample?
Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.

Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below. Original claim: Less than 42% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0204. a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?
A teacher believes that the percentage of students at her high school who go on to college is higher than the rate in the general population of high school students. The rate in the general population of high school students is 30%. In the most recent graduating class at her high school, the teacher found that 90 students graduated and that 40 of those went on to college. Please use the chi-square test to design a complete hypothesis testing process and get appropriate conclusions. (You need to indicate the value of X2obt and df and X2cv)
For a certain hypothesis test, the computed z-value is 2.98 while the critical z-value is 2.33. The corresponding p-value for this test is A. Lesser than the significance level. B. Greater than the significance level. C. Equal to the significance level.
Assume a significance level of α=0.05and use the given information to complete parts (a) and (b) below. Original claim: More than 41% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0259 a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?
A local chess club claims that the length of time to play a game has a mean of 43 minutes or more. Write sentences describing type I and type II errors for a hypothesis test of this claim. A type I error will occur if the actual mean of the length of time to play a game is ▼ equal to less than or equal to not equal to greater than or equal to greater than less than 43 minutes, but you ▼ reject fail to reject the null hypothesis, ▼ Upper H 0 : mu greater than or equals 43H0: μ≥43 Upper H 0 : mu not equals 43H0: μ≠43 Upper H 0 : mu equals 43H0: μ=43 Upper H 0 : mu less than or equals 43H0: μ≤43 Upper H 0 : mu greater than 43H0: μ>43 Upper H 0 : mu less than 43H0: μ<43 .
