- A sample of 137 burglaries indicated that 58 were not via an open or unlocked door or window. At the 0.05 level of significanc, test the claim that less than 50% of the burglaries are not through an open or unlocked door or window.The results section of an article reports the following “IQ scores of the sample differ from the population mean of 100, single sample t (19) = 2.80, p < .05, two tail”.

An urban economist believes that the percentage has increased since then. She randomly selects 55 workers and finds that 10 of them have a travel time to work that is more than 60 minutes. Test the economist's belief at the x = 0.1 level of significance. What are the null and alternative hypotheses? Ho: ▼ versus H₁: (Type integers or decimals. Do not round.)

- just the last part thank you!Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) REsults from five of the students are includedin the graph. Use a significance level to test the claim that there is no difference between the reaction times on the right and left hands.What are the hypothesis for this test?What is the test satistic? Identify the Critical Value(s)What is the Conclusion?The degrees of freedom is critical to computing the p-value for the chi-square goodness of fit. We will discuss the p-value in the next lab. The degrees of freedom for the Chi-Square goodness of fit is equal to (the number of non-zero rows in the table) - 1. The number of non-zero rows is the number of expected values that are non-zero. For example: Phenotype ... Expected ... Disease ... 234 ... Wild-type ... 6743 ... has two rows where the Expected value is non-zero. So the degrees of freedom is 2-1 = 1. Another example: Phenotype ... Expected ... Disease ... 2374 ... Wild-type ... 0 ... has one row where the Expected value is non-zero. So the degrees of freedom is 1-1 = 0. With 0 degrees of freedom, the chi-square test cannot be calculated. A third example (sex-linked): Phenotype ... Expected ... Disease-Male ... 2374 ... Disease-Female ... 9456 Wild-type-Male ... 1001 ... Wild-type-Female ... 235 ... has four rows where the Expected values are…
- The reliability of a test is equal to 0.81. This implies that the validity coefficient related to a criterion of this test can, but does not have to be, be as large as __________.The test statistic for testing HO: mu = 100 against Ha: mu != 100 wast 3.3, with p-value of 0.001. Which of these is the correct conclusion? Since the p-value is very small, we conclud that mu != 100 Since the p-vaue is very smal, we are unable to conlude that mu != 100 Since the p-value is very small, we must conclude the mu = 100 In order to interpret the results, we must first know the sample size. Since the p-value is very small, we are unable to conclude that mu = 100.A local chess club claims that the length of time to play a game has a mean of 23 minutes or more. Write sentences describing type I and type II errors for a hypothesis test of this claim.
