Answer)
Type 1 error means rejection of true null hypothesis
Here
Null hypothesis Ho : u = 8.3
Ha : u > 8.3
A)
So if we will reject Ho even if u = 8.3
We will commit type 1 error
So option E is your type 1 error
B)
Type 2 error means failure to reject false null hypothesis
That is if we fail to reject that u = 8.3 even if it is greater than 8.3
So option D is type 2 error f

Question 30 1 pts Solve the problem. To help consumers assess the risks they are taking, the Food and Drug Administration (FDA) publishes the amount of nicotine found in all commercial brands of cigarettes. A new cigarette has recently been marketed. The FDA tests on this cigarette yielded mean nicotine content of 24.4 milligrams and standard deviation of 2.2 milligrams for a sample of cigarettes. Construct a 95% confidence interval for the mean nicotine content of this...

8. Last year, the mean running time for a certain type of flashlight battery was 8 hours. This year, the manufacturer has introduced a change in the production method which he hopes will increase the mean running time. A random sample of 36 of the new light bulbs was obtained and the mean running time was found to be 8.3 hours with s=1 hours. Do the data provide sufficient evidence to conclude that the mean running time, u, of the...

In the past, the mean gas mileage of a car is 32 mpg. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean gas mileage has increased as a result. The hypotheses are H0: μ = 32 mpg H1: μ > 32 mpg Suppose that the actual average mileage has increased and the results of the sampling fail to lead to rejection of the null hypothesis. Indicate which of...

A manufacturer of electronic kits has found that the mean time required for novices to assemble its new circuit tester is 3.1 hours, with a standard deviation of 0.6 hours. A consultant has developed a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device and the manufacturer needs to decide whether or not to send out the new booklet. The testable hypotheses in this situation are ?0:?=3.1H0:μ=3.1 vs ??:?<3.1HA:μ<3.1. 1. Identify...

In October 2012, Apple introduced a much smaller variant of the Apple iPad, known as the iPad Mini. Weighing less than 1 1 ounces, it was about 50% lighter than the standard iPad. Battery tests for the iPad Mini showed a mean life of 10.25 hours (The Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours. a) Give a mathematical expression for the probability density function of...
