The mean result from some experiment with 50 observations was
1.5 and the standard deviation was 1. Let μ denote the
true mean result. We wish to to test
H 0 : μ = 1 vs
H a : μ ≠ 1 . The p-value is
Group of answer choices
2×P(t49≤3.5)
2×P(t49≥|3.5|)
2×P(t49≤−3.5)
Solution :
This is the two tailed test .
Test statistic = t
= (
-
) / s /
n
= (1.5 - 1) / 1 /
50
Test statistic = 3.5
df = 50 - 1 = 49
The p-value is :
2 x P(t49 > |3.5|)

The mean result of some observations was 50. Let μ denote the true mean result. We wish to test the hypothesis H 0 : μ = 40 vs H a : μ < 40 . Without doing any calculations, the p-value and test conclusion are most likely Group of answer choices Close to 0 so reject the null hypothesis Close to 1 so fail to reject the null hypothesis Close to 0 so fail to reject the null hypothesis Close...
Question 1 On the basis of a sample of size 45, the mean hours freshmen spent on gymnasium per week was calculated to be 3.5 hours and standard deviation of s = 1.2 hours. A researcher wants to test H 0:μ = 4.1 hours against H a: μ < 4.1 hours at 5% significance level. What test would you use here? Group of answer choices Z test Cannot be determined. T test Question 2 On the basis of a sample of...
2. Suppose that we have 9 independent observations from a normal distribution with standard deviation 10. We wish to test Ho : μ-150 vs. H A : μ 150 The best test with level a- 0.05 uses the test statistic T1 =1元-1501 and has a critical value of c 6.53. The test rejects the null hypothesis when T> c (a) Calculate the power of this test against the alternative μ-151. (b) Calculate the power of this test against the alternative...
a data set of 90 observations has a mean of 50 and standard
deviation of 10
ESLIun 14 A data set of 90 observations has a mean of 50 and standard deviation of 10. Which of the following is not necessarily true "The interval (20,80) has at least 80 observations" "The interval (40,60) contains approximately 68% of the observations" "The interval (30,70) has at least 75% of the observations" Impossible to know A Moving to another question will save this...

A random sample of n = 50 observations from a quantitative population produced a mean x = 2.6 and a standard deviation s = 0.35. Your research objective is to show that the population mean y exceeds 2.5. Calculate β = P(accept H0 when μ = 2.6). (Use a 5% significance level. Round your answer to four decimal places.)
A sample of 36 observations is selected from a normal population. The sample mean is 49, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.05 significance level. H0: μ = 50 H1: μ ≠ 50 Q. Interpret the p-value? (Round your z value to 2 decimal places and final answer to 2 decimal places.)
A sample of size 36 is taken from a population with unknown mean and standard deviation 4.5. In a test of H0: μ = 5 vs. Ha: μ < 5, if the sample mean was 4, which of the following is true? (i) We would reject the null hypothesis at α = 0.01. (ii) We would reject the null hypothesis at α = 0.05. (iii) We would reject the null hypothesis at α = 0.10.
The distribution of piston diameters is normally distributed with mean μ inches and standard deviation 5 inches. Engineer Dan takes a sample of 25 pistons from the manufacturing assembly line. Let X1, X2, ..., X25 denote these observations which are iid (independently & identically distributed). a.) What is the probability that X-bar, the sample mean of Dan's 25 observations, is within 1 inch of the population mean μ? b.) Suppose engineer Jane decides to take a sample of 30 observations....
