Conduct the appropriate hypothesis test and compute the test statistic.
A company that produces fishing line undergoes random testing to see if their fishing line holds up to the advertised specifications. Currently they are producing 30pound test line and 20 randomly selected pieces are selected to test the strength. The 20 pieces broke with an average force of 29.1 pounds and a sample standard deviation of 2 pounds. Assuming that the strength of the fishing line is normally distributed, perform the appropriate hypothesis test at a 0.05 significance level in order to determine whether there is sufficient sample evidence to conclude the fishing line breaks with an average force of less than 30 pounds.
Question 25 options:
Yes, because the test statistic is 2.52 

No, because the test statistic is 2.52 

Yes, because the test statistic is 2.01 

Cannot be determined 

No, because the test statistic is 2.01 
Test statistic,
t = (xbar  mu)/(s/sqrt(n))
t = (29.1  30)/(2/sqrt(20))
t = 2.01
Pvalue Approach
Pvalue = 0.0294
As Pvalue < 0.05, reject the null hypothesis.
Yes, because the test statistic is 2.01

Please clear handwriting and highlight answers thank you!! 9. (20 pts) A fishing line manufacturer claims that his new X25 series has an average tensile strength (H) of 25 psi following a normal distribution. To verify his claim, a sample of 25 specimens was tested and yielded the following results: 32, 19, 27, 24, 28, 29, 38, 30, 25, 33, 18, 25, 37,28, 20, 32, 23,21, 25, 19, 23,27, 32, 26,30 this fishing line not meeting the specifications?

PDL2 RD In each problem, you will have to conduct a hypothesis test. For every problem, delineate your answers by putting a box around the following parts of your work: Null hypothesis, Alternative hypothesis, Test statistic, Decision criteria used, Decision made 4. A study was conducted to determine the foam density (g/L) of various brands of refrigerators. A random sample of several refrigerators from each brand were selected and the foam density measured. Use the sample data in the following...
Conduct a hypothesis test for the following scenarios. You may compute the pvalue either by simulation or teststatistic 1) 2) 3) at least one problem must be done by teststatistic conversion at least one problem must be done by simulation simulation should involve at least 10,000 trials. The grading scheme is as follows: Identify and describe the parameter of interest. State the null and alternative hypotheses, using correct notation. Be specific with your parameters. 2pts State the value of the...
What are the null and alternative hypothesis? what is the test statistic? What is the Pvalue? What is the appropriate conclusion? Researchers wanted to see if a certain image in ads affected people's ability to remember the item being advertised. They found two ads for each of 10 similar items, one with the image and one without. Then they showed the ads in random order to 39 randomly selected people for one minute and asked them to list as many...
Not sure of my answers Suppose you wish to conduct a test of the research hypothesis that the median of a population is greater than 73. You randomly sample 20 measurements from the population and determine that 13 of them exceed 73. Set up and conduct thee appropriate test of hypothesis at the 0.10 level of significance. Be sure to specify all necessary assumptions. What are the null and alternative hypotheses for this hypothesis tast? OA. Ho: n13 He :...
5. A manufacturing company produces electric insulators. To test the strength of the insulators, you apply a force to an insulator until it breaks. You measure the force by observing how many pounds are required to break the insulator. You collect the force data for a random sample of 30 insulators selected for this experiment. The data is in the Excel file for this assignment in the tab Force. a. Construct a 95% confidence interval estimate for the population mean...
A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. The data shown below represent the amount of force required to...
Please solve both questions. Instructions are at the top For the problems on the NEXT page you must conduct a complete hypothesis test procedure for these problems making it clear what formula was being used. Be sure to formulate both hypotheses, identify critical values and rejection regions where appropriate, your test statistic, as well as stating your final conclusion IN NONTECHNICAL TERMS (Translation Assume you are stating your conclusion to somebody with no knowledge of statistics.)!! A simple random sample...
Question 4 A manufacturing company produces electrical insulators. If the insulators break when in use, short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is meas ured by observing the number of pounds of force applied to the insulator before it breaks. In the Excel file provided "Data Assignment 2" there are the data from 30 insulators subjected to...
