The Rockwell hardness index for steel is determined by pressing a diamond point into the steel and measuring the depth of penetration The manufacturer claims that this steel has an average hardness index of 64. A competitor decides to check out this claim. Formulate null and alternative hypotheses that the competitor should check in order to test the manufacturer’s claim. What type of test should be used?

To test the claim that the resistance of electric wire can be reduced by more than 0.050 ohm by alloying, 25 values obtained for alloyed wire yielded an average of 0.083 ohm with s = 0.003 ohm, and 25 values obtained for standard wire yielded an average of 0.086 ohm with s = 0.002 ohm. Use 5% level f significance to determine whether the claim has been substantiated. What is the computed value and decision?
What is the average NO3- concentration at the upslope site (3 decimal places)? What is the average NO3- concentration at the downslope site ( 3 decimal places)? Given the EPA drinking water quality standard is 10 mg/L of nitrate, is the upslope site safe to drink based only on nitrate content? (Enter yes or no) Is the downslope site safe to drink, based only on NO3- concentration? (Enter yes or no) Assuming the two sites are hydrologically well connected, the transit time between the two sites is fast, and the two sites cannot be treated as independent samples, what kind of t-test should be performed to show that the upslope site is greater than the downslope site? Enter the letter of your answer choice in the answer blank A. one-tailed unpaired t-testB. two-tailed unpaired t-testC. one-tailed paired t-testD. two-tailed paired t-test What is the calculated t statistic, rounded to 4 decimal places?

The Us food and Drug administration has a limit for mercury content in fish of 1.0ppm (parts per million) while in Canada the limit is 0.5 ppm. Using the variable average mercury in the Florida lakes dataset to test whether there is evidence that average mercury level of fish ( large mouth Bass) in Florida lakes is less than 1.0ppm and whether there is evidence that average mercury level of fish in Florida lakes is less than 0.5ppm. STATE THE NULL AND ALTERNATIVE HYPOTHESES? GIVE THE TEST STATISTICS AND P-VALUE? round the test statistic to two decimal places and the p-value to three decimal places. DOES THIS SAMPLE PROVIDE EVIDENCE THAT THE AVERAGE MERCURY LEVEL OF FISH (LARGE MOUTH BASS) IN FLORIDA LAKES IS LESS THAN 1.0PPM? LESS THAN 0.5 PPM : STATE THE NULL AND ALTERNATIVE HYPOTHESES. GIVE THE TEST STATISTICS AND P-VALUE ? round the test statistic to two decimal places and the p-value to three decimal places. DOES THIS SAMPLE PROVIDE EVIDENCE THAT THE AVERAGE MERCURY…
What is the appropriate conclusion for this test? (Do not reject OR reject) H₀ and conclude that there (is or is not) sufficient evidence that mice with an average life span of 32 months will live to be (less or greater) than 42 months old when 40% of the calories in their diet are replaced by vitamins and protein.
A certain percentage of items produced have some defects. To estimate the defect rate p, a collection of 100 items sampled from production revealed that 10 items contained suchdefects.1. Formulate and test the appropriate null H0 and alternative hypotheses H1 to verify the claim that the defect rate is smaller than 0.15 at level α = 0.1 2. Find the P-value. Based on the P-value, can you reject H0 at level α = 0.01?
The P value is_. Round to three decimal places as needed. to test the null hypothesis Should we reject or do not reject the hypothesis?
Suppose we want to compare the length of hospital stay for patients with the same diagnosis at two different hospitals. The results are shown in Table 9.10. A) Why might a t test not be very useful in this case? B)Carry out a nonparametric procedure for testing the hypothesis that lengths of stay are comparable in the two hospitals
According to research, of all U.S. households that owned at least one TV set, 83% had two or more sets. A local cable company canvassing the town to promote a new cable service found that of the 295 households visited, 230 had two or more TV sets. At (alpha) = 0.10, is there sufficient evidence to conclude that the proportion is less than the one in the report? A. State the hypotheses and identify the claim with the correct hypothesis. B. Find the critical value(s). C. Compute the test value. D. Make the decision. E. Summarize the results.
It has been claimed from previous studies that the average diameter of ball bearings from this manufacturing process is 2.30 cm. Based on the sample of 50 that you collected, is there evidence to suggest that the average diameter is greater than 2.30 cm? Perform a hypothesis test for the population mean at alpha = 0.01 Define the null and alternative hypothesis for this test in mathematical terms and in words ,report the level of significance, include the test statistic and the P-value and provide your conclusion and interpretation of the results.
