Are both Ho and H1 are sigma > 1.2cm? It says exceeds 1.2 cm, which means that both are sigma > 1.2cm. Confused on why we would test two of the same thing. Thanks.
To Test :-
H0 :-
H1 :-
Test Statistic :-
χ2 = ( ( 25-1 ) * 2.25 ) / 1.44
χ2 = 37.5
Test Criteria :-
Reject null hypothesis if
= 36.415
= 37.5 > 36.415 , hence we reject the null hypothesis
Conclusion :- We Reject H0
Decision based on P value
P value = P ( χ2 > 37.5 ) =
0.039
Reject null hypothesis if P value < α = 0.05
Since P value = 0.039 < 0.05, hence we reject
the null hypothesis
Conclusion :- We Reject H0
There is sufficient evidence to support the claim that standard deviation of the length is exceeds 1.2 cm.

1. A company produces surveying tapes of claims that the standard deviation of the length of their 100-ft tapes is 2.5 ft. UTA Civil Engineering department decides to test this claim by taking a sample of 35 tapes and checking their lengths. They found that the standard deviation of the sample is 2.8 cm. Does this undermine the company’s claim? Confidence level is 95%.

SSCE 2193 c) A company produces metal pipes of a standard length, and claims that the standard deviation of the length is at most 1.1 cm. One of its clients decides to test this claim by taking a sample of 25 pipes and checking their lengths. They found that the standard deviation of the sample is 1.5 cm. Can we accept the company's claim at 2.5% significance level? (5 marks) QUESTION...
Random samples of two species of iris gave the following petal lengths (in cm). x1, Iris virginica 5.1 5.9 4.5 4.9 5.7 4.8 5.8 6.4 5.7 5.9 x2, Iris versicolor 4.5 4.3 4.7 5.0 3.8 5.1 4.4 4.2 (a) Use a 5% level of significance to test the claim that the population standard deviation of x1 is larger than 0.55. What is the level of significance? State the null and alternate hypotheses. H0: σ = 0.55; H1: σ > 0.55...
1. A bearing used in an automotive application is supposed to have a nominal inside diameter of 3.81 cm. A random sample of 25 bearings is selected and the average inside diameter of these bearings is 3.8037 cm. Bearing diameter is known to be normally distributed with standard deviation σ 0.03 cm. (a) Compute a 95%-confidence interval for the mean inside diameter. (b) Test the hypothesis H0 : μ = 3.81 versus H1 : μ关3.81 using α-001. What is the...

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 25.5 with a standard deviation...
