- Spacers are manufactured to the mean dimension and tolerance shown in Figure 29-12. An inspector measures 10 spacers and records the following thicknesses: 0.372" 0.376" 0.379" 0.375" 0.370" 0.373" 0.377" 0.378" 0.371" 0.380" Which spacers are defective (above the maximum limit or below the minimum limit)? All dimensions are in inches.What is the significance of the golden ratio?A new machine is set or calibrated to fill tubes of toothpaste at precisely 6.75 ounces. Then, once the machine is running, a sample of six tubes is taken every three hours and weighed with the following results: WEIGHT OF TOOTHPASTE Time 7 am 6.69 6.68 6.79 6.77 6.74 6.76 10 am 6.71 6.72 6.71 6.76 6.75 6.74 1 pm 6.66 6.68 6.67 6.71 6.76 6.78 4 pm 6.73 6.74 6.72 6.76 6.78 6.75 7 pm 6.75 6.73 6.75 6.77 6.79 6.75 The measurement of quality is based on _______.

- A state highway patrol official wishes to estimate the number of legally intoxicated drivers on a certain road. a) How large a sample is needed in order to be 99% confident that the sample proportion will not differ from the true proportion by more than 5%? b) Repeat part (a) assuming previous studies found that 75% of the drivers on this road are legally intoxicated.A machine being used for packaging seedless golden raisins has been set so that on average, 15 ounces of raisins will be packaged per box. The quality control engineer wishes to test the machine setting and selects a sample of 30 consecutive raisin packages filled during the production process. Their weights are recorded as follows: 15.2 15.3 15.1 15.7 15.3 15.0 15.1 14.3 14.6 14.5 15.0 15.2 15.4 15.6 15.7 15.4 15.3 14.9 14.8 14.6 14.3 14.4 15.5 15.4 15.2 15.5 15.6 15.1 15.3 15.1 At the 5% level of significance, is there evidence that the mean weight per box is different from 15 ounces? Use the 5-step classical rejection region critical value decision rule for this problem. You may use the TI-84 t-test option to calculate the test statistics (tStat). For the rejection region approach recall that we look up the tcritical on the t table, tα,n-1 for a 1 tail and tα/2,n-1 for a 2 tail test. State the meaning of µ, then list the 5 steps. See lecture #14. If you reject Ho, construct a (1-α)%…Suppose an urn contain 8 balls find the number of ordered sample's of size 3 without replacement. answer correctly.
