A manufacturer of lightbulbs advertises that, on average, its long-life bulb will last more than 5000 hours. To test the claim, a statistician took a random sample of 100 bulbs and measured the amount of time until each bulb burned out. *Refer to the table below. a. State the null and alternative hypotheses. b. Compute the value of the test statistic. c. Compute the critical value at the level of significance of 0.01. d. Find ?-value. e.

The manager of the Isiksan factory, where light bulbs are produced, believes that the life of the bulbs they produce is at least 20,000 Hours. The manager selected and tested 100 bulbs as rassal to test his thinking. The average life time and standard deviation found as a result of the test are given in the table below. at the 90% confidence level, the manager's right or wrong will be investigated. Accordingly, the Z value (Zhes) to be calculated to test the hypothesis is given correctly in which case. Average Life=20300 Saat G.D=0,9 Standard Deviation=2800 Saat Zhes=?

00:01 Student, let's discuss the question first.
00:03 Here we will get a d9 value that is equals to 9 multiple n plus 1 by 10th observation.
00:12 10th value of the observation, of the observation.
00:21 So we will get 9 .45 divide by 10th observation.
00:30 So 9 .45 divided by 10, 9 multiple 45 divided by 10 observation.
00:38 So that is equals to 40 .5th observation...
