The following data set was collected from a survey  60, 56,46,55,42,43,57,46,49,56,55,59,49,41,52,53,46,51,54,43,41 If a frequency distribution is to be constructed with classes 40-44,  45-49,  50-54,  55-59, and 60-64  what is the frequency of the 40-44 class

(c) Based on what we know about Observation B, if the cutoff value is lowered to 0.2, what happens to the values of sensitivity and specificity? Explain. Use the ROC curve to estimate the values of sensitivity and specificity for a cutoff value of 0.2. If required, round your answers to three decimal places. Do not round intermediate calculations. Answer Part C, there are no other parts here. I have the sensitivity already and is equal to 1. What is the specificity??If you are not 100% sure you are right, do not attempt this is frustrating. The cutoff value has changed from 0.5 to 0.2. The sensitivity is 1 which is correct. I need help with the specificity. Sensitivity does not equal 1/14 and specificity does not equal 1/31 so don't answer that and do not answer any other parts just answer part C.

A standard error is essentially a standard deviation, specifically, the standard deviation of the sampling distribution of the estimate of the population parameter.     d. All of these choices are correct characterizations of a typical standard error.
