Much research has been conducted by experts regarding the size of crocodile tails. Researchers gathered a small sample of five crocodiles and recorded that the standard deviation of the sample tail lengths is 2.314 feet.

(a) Construct a 94 percent confidence interval for the variance of tail lengths.

(b) Find a 99 percent confidence upper bound for the standard deviation

Census ~ In 2020, Pew Research conducted a poll to examine how likely a person was to participate in the 2020 US Census based on their age. In a random sample of US adults aged 50 years or older, 85.63% said they were likely to participate in the Census. The estimated standard error of the sample proportion is 0.0064. A normal distribution can be used to model the sampling distribution of sample proportion. The researchers wish to construct a 95%...

A study was conducted to estimate the effect of college student employment on academic performance. In a random sample of 15 working students, the mean GPA was 2.4 with a standard deviation of 0.05. In a random sample of 13 nonworking students, the mean GPA was 2.3 with a standard deviation of 0.03. Assume the populations are normal with equal variances. Round your critical value to three decimals. Enter your answers rounded to four decimal places. (a). The pooled sample...

Census ~ In 2020, Pew Research conducted a poll to examine how likely a person was to participate in the 2020 US Census based on their age. In a random sample of US adults aged 18 - 49 years old, 67.45% said they were likely to participate in the Census. The estimated standard error of the sample proportion is 0.0148. A normal distribution can be used to model the sampling distribution of sample proportion. The researchers wish to construct a...

*Please Answer All * 1. A company has developed a new type of light bulb and wants to estimate its mean lifetime. A simple random sample of 12 bulbs had a sample mean lifetime of 651 hours with a sample standard deviation of 31 hours. It is reasonable to believe that the population is approximately normal. Find the lower bound of the 95% confidence interval for the population mean lifetime of all bulbs manufactured by this new process. Round to...

In a survey conducted by Essential Baby, a random sample of 14 mothers was conducted to estimate the standard deviation of ages, in weeks, at which babies begin to crawl. A normality test of the resulting data is provided below. Use this sample to construct a 95% confidence interval for the standard deviation of the age at which babies begin to crawl. Summary Statistics N=14, Mean= 37.214, StDev=9.744, Minimum= 24.000, Maximum=56.000, AD-Value=0.27, and P-value=0.6261 Ho:Data follow a normal distribution H1:...

Answer all parts of question 1, each part is worth a corresponding point value. 1a On June 23, 2003, a huge, unidentified sea creature was found washed ashore on a beach in Chile. The animal was described a 40-foot long mass of rotting gray flesh that scientists estimated to weigh about 13 tons. Some scientists believed that the creature was a giant octopus, despite the absence of obvious tentacles. The largest octopi are found along the northern Pacific coast of...

Researchers conducted a study to determine whether magnets are effective in treating back pain. The results are shown in the table for the treatment​ (with magnets) group and the sham​ (or placebo) group. The results are a measure of reduction in back pain. Assume that the two samples are independent simple random samples selected from normally distributed​ populations, and do not assume that the population standard deviations are equal. Complete parts​ (a) and​ (b) below. Use a 0.050.05 significance level...
