Question

A fabric manufacturer believes that the proportion of orders for raw material arriving late isp= 0.6. If a random sample of 10 orders shows that 4 or fewer arrived late, the hypothesis thatp= 0.6should be rejected in favor of the alternativep <0.6. (a)Find the probability of committing a type II error for the alternativesp= 0.5 (b)Find the probability of committing a type I error if the true proportion isp= 0.6.

Answer #1

The proportion of residents in Phoenix favoring the building of
toll roads to complete the freeway system is believed to be
p = 0.3. If a random sample of 15 residents shows that one
or fewer favor this proposal, we will conclude that p <
0.3.
Find the probability of type I error if the true proportion is
p = 0.3.
Find the probability of committing a type II error with this
procedure if p = 0.2.

Question 1
The production manager of a camera manufacturer claims that
their
latest digital camera is able to focus in just 0.0025 seconds on
the
average. A random sample of the focus time in seconds for 20
cameras
is collected and the times are recorded as follows:
0.0033
0.0028
0.0021
0.0032
0.0020
0.0025
0.0026

0.0021
0.0023
0.0028
0.0031
0.0028
0.0035
