Answer and explanation:

Not sure if the question is complete or valid but I will explain each option:

Let's assume the question asks which of the options would provide a negative result of -25( as no option evaluates to -255)

A. There would be a negative result here since all golfers have a negative score of -5 after 9 holes, and therefore a total score of -25 for all five golfers

B. Temperature increases by 25 degrees after 5 hours hence 5 degrees increase for every 1 hour. This would obviously give a positive result.

C. A football team gains 25 yards in the first play and loses 5 yards in the second but has a result of 5 yards gained in total. Hence there was a penalty of losing 20 yards for a loss of 5 yards= 25 yards- 20 yards= 5yards

D. Alyson withdraws $25 every week for 5 weeks, therefore she withdraws $125 in 5 weeks. This would be a negative result of -$125.

"You measure 34 dogs' weights, and find they have a mean weight of 67 ounces. Assume the population standard deviation is 13.5 o
liraira [26]

Answer:

The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96*\frac{13.5}{\sqrt{34}} = 4.54

The lower end of the interval is the sample mean subtracted by M. So it is 67 - 4.54 = 62.46 ounches.

The upper end of the interval is the sample mean added to M. So it is 67 + 4.54 = 71.54 ounces.

The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.
