A survey of 700 non-fatal accidents showed that 163 involved the use of a cell phone. Find a point estimate for p, the population proportion of non-fatal accidents that involved the use of a cell phone.
Given that, a survey of 700 non-fatal accidents showed that 163 involved the use of a cell phone.
A point estimate for p, the population proportion of non-fatal accidents that involved the use of a cell phone is,
=> Point estimate =0.2329 (rounded to 4 decimal places)

VULJHUIV 17 A survey of 700 non-fatal accidents in the United States showed that about 23% involved uninsured drivers. The margin of error is 3 percentage points with a 95% confidence. Does the confidence interval support the claim that at least 25% of non-fatal accidents in the United States involve uninsured drivers. Why? No; the interval does not support this claim because the interval contains values that are above 25% O No; the interval does not support this claim because...

A researcher wishes to estimate the average blood alcohol concentration (BAC) for drivers involved in fatal accidents who are found to have positive BAC values. He randomly selects records from 51 such drivers in 2009 and determines the sample mean BAC to be 0.16 g/dL with a standard deviation of 0.070 g/dL. Complete parts (a) through (d) below. c) Determine and interpret a 90% confidence interval for the mean BAC in fatal crashes in which the driver had a positive...
