* Mean
457.6230 = 15.85
* Median
The middle variables are 15.98 &16.00 therefore, 15.98+162 = 15.99
* Standard deviation
7553.165-(457.622/30) 30-1 = 4.44362
Question 2
95% confidence level
4.4436230 = 0.81129
Question 3
1 H0: µ ≥16
2 Ha: μ < 16
3 α = 0.01
4 Sample statistics
Standard error - sn =4.4436230 = 0.811290
Degree of freedom (DF) – n-1 30-1= 29
T calculated - (x - μ) / SE (15.85-16)0.81129 = -0.18489
Given the alternative hypothesis (μ < 16), we want to know whether the observed sample mean is small enough to cause us to reject the null hypothesis.
The observed sample mean produced a t statistic test statistic of -0.18489. We use the t Distribution Calculator to find P (t < -0.18489) = 0.253. This means we would expect to find a sample mean of 15.85 or smaller in 25.3% of our samples, if the true ounces were 16. Thus, the P-value in this analysis is 0.19.
Interpret results. Since the P-value (0.253) is greater than the significance level (0.01), we cannot reject the null hypothesis.
Conclusion: There is evidence from these data and results to suggest that a bottle contains less than 16 ounces.
Question 4
The causes for less ounces in the soda can be due to inefficiency with the machines, due to old age of the machines it can lead ...
