Provide an appropriate response.A survey of 100 fatal accidents showed that in 18 cases the driver at fault was inadequately insured. Find a point estimate for p, the population proportion of accidents where the driver at fault was inadequately insured

Provide an appropriate response.Use a t-test to test the claim μ > 14 at α = 0.005, given the sample statistics n = 25, = 15, and Round the test statistic to the nearest thousandth.

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed and the parameter that is being tested.H0: p = 0.94 H1: p > 0.94

Billy Joe’s Ice Cream store is interested how the weather affects their ice cream sales. The following table represents data from randomly selected spring, summer, and fall months over a few years. The number of days in the month with no cloud cover and the numbers of ice cream cones sold for that month were recorded. Determine if there is a linear correlation between the number of days with no cloud cover and the number of ice cream cones sold. Statistical Method:  Is there significant linear correlation?  Yes or No?   Using the data above, find the regression line, and preict the number of cones sold when a month has 13 days with no cloud cover. Regression Line:  Number of cones sold:
