breaking strength is 8367 pounds with a standard deviation of 223 pounds. A dotplot of the data is shown betow. (a) Describe the distribution of the breaking strength of the ropes in this sample. (b) Construct and interpret a \( 98 \% \) confidence interval for the true mean tensile breaking strength of this brand of \( 12 \mathrm{~mm} \) rope. 25 ropes will differ by less than 150 pounds?

- Since the actual dotplot is not visible in this text format, we will assume a typical interpretation based on the provided mean and standard deviation. Generally, you would look for the shape, center, and spread of the distribution in the dotplot. - Show more…

The tensile strength of manila ropes follows a normal distribution. A random sample of 16 manila ropes has a sample mean strength 4450 kg and sample standard deviation 115 kg. Suppose that we want to test whether the mean strength of manila rope is less than 4500 kg. At a significance level a = 0.05, the value of the test statistic and the conclusion for this test are: 1.739; Reject H0 -1.753; Reject H0 -1.739; Do not reject H0 -1.739; Reject H0 -1.753; Do not reject H0

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 98 pounds. A random sample 60 of newly manufactured cables has a mean breaking strength of 1950 pounds. Based on this sample, find a 99% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit.
