A machine is used to fill bottles. A company is concerned with the variability in the number of ounces filled. The standard deviation of weight is known to be 0.06 oz. An improvement is implemented under new company leadership, after which a random sample of 16 bottles is selected and squared sample variance found to be 0.077 oz. Find the 95% confidence interval on standard deviation.

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
