A manufacturer claims that fewer than 6% of its fax machines are defective. In a random sample of 100 such fax machines, 5% are defective. Find the P-value for testing the manufacturer's claim. a.0.34 b.0.33 c.0.06 d.0.16 e.0.17
Homework Answers
Ans:
Test statistic:
z=(0.05-0.06)/sqrt(0.06*(1-0.06)/100)
z=-0.42
p-value=P(z<-0.42)=0.34
Correct option is 0.34

A soft-drink manufacturer claims that its 12-ounce cans do not contain, on average, more than 30 calories. A random sample of 68 cans of this soft drink, which were checked for calories, contained a mean of 32 calories with a standard deviation of 3 calories. Does the sample information support the alternative hypothesis that the manufacturer's claim is false? Use a significance level of 5%. Find the range for the p-value for this test. What will your conclusion be using...

A manufacturer of automobile headlights claims that 10% of a batch of these headlights are defective. A quality control inspector tests a random selection of 300 headlights in the batch. The number of defective headlights in this random sample is 35, which is more than expected. Estimate the probability of getting at least 35 defective lights in a random sample of 300. Based on the result, does it appear that the manufacturer’s claim of 10% defectiveness is accurate? Was there...

A manufacturer claims that the mean lifetime of its lithium batteries is 1100 hours but a group of homeowners believe their battery life is different than this manufacturer's claim. A homeowner selects 35 of these batteries and finds the mean lifetime to be 1080 hours with a standard deviation of 80 hours. Test the manufacturer's claim. Use a 10% level of significance and the p-value approach. Round the test statistic to the nearest thousandth. Need hypothesis testing, values of symbols,...

A surgical clamp manufacturer claims that only 10% of its parts are defective (p = 0.10). Hospital critics claim the defect rate is higher (p > 0.10). Testing of 500 randomly selected parts yields a Z statistic of -4.0. a & b) Write out the null and alternative hypotheses c) Will the computation result in a one- or two-tailed test (on a Bell curve)? d) What does the negative z-score indicate regarding the critical region of the test (on a...

A manufacturer claims that the mean lifetime of its lithium batteries is less than 1095 hours. A homeowner selects 27 of these batteries and finds the mean lifetime to be 1065 hours with a standard deviation of 76 hours. Test the manufacturer's claim. Use a = 0.02. P-value = 0.112 > 0.02; do not reject H0; There is not enough evidence support the claim that mean is less than 1500. ОА P-value = 0.025 0.02, do not reject HO, There...

6. WHAT IS THE TEST STATISTIC? A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at α = 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects.

A cigarette manufacturer claims that the average nicotine content of their new brand XXX is at most 1.35 mg. It would be unwise to reject the manufacturer's claim without strong contradictory evidence. An appropriate problem formulation is to test A random sample of 100 brand XXX cigarettes are tested and the sample standard deviation and sample mean are found to be 0.07 mg and 1.361 mg, respectively. Assuming the central limit theorem applies and s ≈ σ, find the p-value...
