Answer 1

Answer #1

1)The villagers first error was a type ii error and their second error was a type i error.

Type I error: Rejecting Ho when Ho is true

Type ii error: Accepting Ho when Ho is false

2) The null hypothesis is the boy cried wolf when there was not one

3) If F is grater than F critical value, then P value will be less than level of significance (alpha)

Problem 1: Medicare would like to test the hypothesis that the average monthly rate for one-bedroom assisted-living facility is equal to $3,300. A random sample of 12 assisted-living facilities had an average rate of $3,690 per month. The standard deviation for this sample was $530. Medicare would like to set α = 0.05. The correct hypothesis statement for this hypothesis test would be H0: μ ≥ $3,300; H1: μ < $3,300. H0: μ = $3,300; H1: μ ≠ $3,300. H0:...

1. The mean number of days it takes an employer to approve medical leave is believed to be about ten. Members of a collective bargaining unit do not believe this figure. They randomly survey eight employees. The number of days they took to approve medical leave are as follows: 12; 4; 15; 3; 11; 8; 6; 8. Let X = the number of days the employer took to approve medical leave. (a) Identify a null and alternative hypothesis. (b) Determine...

6. A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho: p = 0.75 vs. Ha: p ≠ 0.75. If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7. Return to Question 6. The fact that the test statistic is negative tells...

When Ho: p = 0.25 is true and n = 10 only, the probability of cornmitting Type I error is about 0.08 which is substantially greater than the fixed α = 0.05. This is an issue for practical use of the hypothesis testing. By changing the null value 0.01 p 0.5 and the sample size 10Sn 1000, investigate the probability of committing Type I error. a. Complete the following table by the probability of committing Type I error. (First, write...
