The true proportion of defectives in a certain manufacturing process is ? = 0.08. Find the probability that a sample of size ? = 150 items yields a sample proportion (?̅) between 0.06 and 0.10.
=P[-0.9<Z<0.9]
=0.8159-0.1841..................by using Z table.
=0.6318

4. How large a sample would be necessary to estimate the true proportion of defectives in a large population within +4%, with 95% confidence? (Assume a pilot sample yields p = 0.14) *
2. (2marks) For a certain manufacturing process, it is known that, on the average, 1 in every 100 items is defective. Among 25 inspected items, what is the probability that two items were found defectives?
Compute 95% confidence intervals, using both methods on page 297, for the proportion of defective items in a process when it is found that a sample of size 100 yields 8 defectives.
The true mean of the cost of a certain type of surgeries is ? = 5000 riyals. Also, it is known that the population standard deviation of the costs is ? = 150. Find the probability that a sample of size ? = 60 surgeries yields a sample mean (?̅) more than 4950 Riyals.
The following data gives the number of defectives in 5 independent samples from a production process. The samples are of varying size. Draw appropriate chart and comment on the process Sample number Sample size Number of defectives 1 2000 400 2 1000 150 3 1000 120 4 600 80 5 400 50
A manufacturer produces test tubes from two independent processes. Process 1 produces 10% defectives while Process 2 produces 15% defectives. Random samples of size 100 are obtained from each process on a daily basis. What is the probability that the sample from Process 1 has fewer defectives than the of Process 2?
Partial Question 1 3/4 pts A certain process for manufacturing integrated circuits has been in use for a period of time, and it is known that 12% of the circuits it produces are defective. A new process that is supposed to reduce the proportion of defectives is being tested. In a simple random sample of 100 circuits produced by the new process, 11 were defective. Match the following: The population of interest Integrated circuits mad Parameter of interest proportion of...

The number of defectives in a certain production process was observed for a period of time and classified by day of the week in the following table: Monday 409 Tuesday 310 Wednesday 298 Thursday 315 Friday 586 What is the probability that a defective item was produced on a Monday or a Friday? a. 0.16 b. 0.31 c. 0.47 d. 0.52
Twenty five samples of size 1000 each were drawn from a manufacturing process and the number of defectives in each sample was counted. The average sample proportion was 0.05. The upper control limit for the p chart is:
