In preparation for upcoming wage negotiations with the union, the managers for the Bevel Hardware Company want to establish the time required to assemble a kitchen cabinet. A first line supervisor believes that the job should take 40 minutes on average to complete. A random sample of 22 cabinets has an average assembly time of 47 minutes with a population standard deviation of 13 minutes. Is there overwhelming evidence to contradict the first line supervisor’s belief at a 0.10 significance level? Assume the population of assembly times is approximately normally distributed. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.

Question

In preparation for upcoming wage negotiations with the union, the managers for the Bevel Hardware Company want to establish the time required to assemble a kitchen cabinet. A first line supervisor believes that the job should take 40 minutes on average to complete. A random sample of 22 cabinets has an average assembly time of 47 minutes with a population standard deviation of 13 minutes. Is there overwhelming evidence to contradict the first line supervisor’s belief at a 0.10 significance level? Assume the population of assembly times is approximately normally distributed.

Step 2 of 3 :

Compute the value of the test statistic. Round your answer to two decimal places.

Company want to establish the time required to assemble a kitchen cabinet. A first line supervisor
believes that the job should take 40 minutes on average to complete. A random sample of 22 cabinets
has an average assembly time of 47 minutes with a population standard deviation of 13 minutes. Is there
overwhelming evidence to contradict the first line supervisor's belief at a 0.10 significance level? Assume
the population of assembly times is approximately normally distributed.
Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
