Question 27 options:

A researcher selects a sample of n = 25 from a normal population with µ = 80 and σ = 20. If the treatment is expected to increase scores by 6 points, what is the power of a two-tailed hypothesis test using α = .05?

Enter the result for each step below:

Step 1: Enter the standard error, σ_M (enter a number with 5 decimal places using only the keys "0-9" and "."):

Step 2: Enter the z-score that marks the boundary of the positive critical region under the null hypothesis (hint, if you drew out the distribution, the boundary marks the beginning of the shaded area on the right side) (enter a positive number with 5 decimal places using only the keys "0-9" and "."):

Step 3: What is the smallest sample mean that would fall within the positive critical region defined by the boundary you entered in the last blank (enter a number with 5 decimal places using only the keys "0-9" and ".")?

Step 4: Enter the z-score that would correspond to the sample mean you entered in the previous blank under the alternative hypothesis (enter a number with 5 decimalplaces using only the keys "0-9" and "."):

Final Answer: Enter the statistical power implied by the z-score from the previous blank as a proportion (e.g., 0.5111 not 51.11%) (enter a number with 5 decimalplaces using only the keys "0-9" and "."):

A random sample was taken of 27 concrete beams produced by a certain manufacturer. Each beam in the sample was weighed (in Kg) to assess whether the concrete content was up to industry standards.Sample mean=68.4, Standard Deviation=2.6.

Construct a 95% confidence interval for the true average weight of concrete beams coming from this manufacturer. Interpret this confidence interval in the form of a sentence.The manufacturer claims that their manufacturing process is calibrated to produce average beam weights that satisfy the industry requirement of (at least) 69.5Kg per beam.Test the validity of the manufacturer’s claim using the data collected. Summarise your findings in the form of a probability statement, and write your conclusions in a way that is understandable to a quality control officer.Assess the validity of the assumptions needed to carry out the calculations.

Assuming the degrees of freedom equals 27, select the t value from the t table.

27.) Tom is in respiratory arrest due to an electrical shock. Why does a Good Samaritan have about 4 to 5 minutes to begin CPR?
