  1. The FDA has established that the concentration of a certain pesticide in apples may not exceed 10 ppb. A random sample of 100 apples was taken from a major orchard. The sample mean is 10.03 ppb and the sample standard deviation is 0.12 ppb. Are the apples within FDA requirements?

    1. (a) State the null hypotheses H0. (Your answer should be an equation or an inequality in- volving μ).

    2. (b) State the alternative hypotheses Ha. (Your answer should be an equation or an inequality involving μ).

    3. (c) Perform a one-sample t-test to test your null hypothesis. Show the details of your calcu- lation.

    4. (d) Do you reject or fail to reject your H0. Explain.

The FDA has established that the concentration of a pesticide in apples may not exceed 10 parts per billion (ppb). A random sample of 25 apples from a major orchard had an average pesticide content of 9.9 ppb, with a standard deviation of 0.5 ppb. The calculated t-statistic is 1, with an associated P-value for the one-tailed test of 0.164. The mean concentration of a pesticide of the samples= Tries 0/2 The standard deviation is = Tries 0/2 The sample...

To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen is then measured, yielding a sample average penetration of x = 53.2 and a sample standard deviation of s = 4.2. The conduits were manufactured with the specification that true average penetration be at most 50 mils. They will be used unless it can be demonstrated conclusively that...

The desired percentage of SiO2 in a certain type of aluminous cement is 5.5. To test whether the true average percentage is 5.5 for a particular production facility, 16 independently obtained samples are analyzed. Suppose that the percentage of SiO2 in a sample is normally distributed with σ = 0.32 and that x = 5.21. (Use α = 0.05.) (a) Does this indicate conclusively that the true average percentage differs from 5.5? State the appropriate null and alternative hypotheses. H0:...

Unfortunately, arsenic occurs naturally in some ground water†. A mean arsenic level of μ = 8.0 parts per billion (ppb) is considered safe for agricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. A random sample of 31 tests gave a sample mean of x = 7.0 ppb arsenic, with s = 2.2 ppb. Does this information indicate that the mean level of arsenic in this well...
