**Educational Content: Estimating Chi-Square Critical Values and Confidence Intervals**In this exercise, we will find the number of degrees of freedom, the critical values \(\chi^2_L\) and \(\chi^2_R\), and the confidence interval estimate of \(\sigma\). We assume a simple random sample has been selected from a population with a normal distribution.**Context:**- For nicotine in menthol cigarettes, with 99% confidence: - Sample size \(n = 25\) - Sample standard deviation \(s = 0.23\) mg**Steps:**1. **Determine Degrees of Freedom:** - Formula: \(df = n - 1\) - Enter the whole number.2. **Find Chi-Square Critical Values:** - \(\chi^2_L\): Left critical value (round to three decimal places). - \(\chi^2_R\): Right critical value (round to three decimal places).3. **Calculate Confidence Interval for \(\sigma\):** - Use the relevant chi-square values to determine the confidence interval. - Input the values, rounding to two decimal places.**Helpful Resource:**- Access the Chi-Square critical values table via the provided link to ensure accurate calculations.---**Note:** This educational guide is meant to assist in filling out the details needed for statistical analysis. Steps should be followed as outlined to ensure precise estimation of the confidence interval and critical values.

Given that the sample size is, n =25 Sample standard deviation, s = 0.23 The confidence level is, c…

PLEASE HELP ME TO GET THE HISTOGRAM, FREQUENCY POLYGON AND PIE CHART OF THE PICTURE BELOW. THE SOLUTION WAS PROVIDED BELOW: The mean gives the average of all the observation and it calculated for grouped frequency table as : x¯=∑fx∑f The median is the middle value of the data set and it calculated for grouped frequency table as : Md=l+n2-cf×h where n is the number of observation, l is the lowest boundary and f is the frequency and h is the class width.

An automobile assembly line operation has a scheduled mean completion time, μ , of 15.1 minutes. The standard deviation of completion times is 1.7 minutes. It is claimed that, under new management, the mean completion time has decreased. To test this claim, a random sample of 90 completion times under new management was taken. The sample had a mean of 14.7 minutes. Can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? Assume that the standard deviation of completion times has not changed. Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places, and round your responses as specified in the table.
