The claims department at Wise Insurance Company believes that younger drivers have more accidents and, therefore, should be charged higher insurance rates. Investigating a sample of 1,200 Wise policyholders revealed the following breakdown on whether a claim had been filed in the last 3 years and the age of the policyholder. Is it reasonable to conclude that there is a relationship between the age of the policyholder and whether or not the person filed a claim? Use the .05 significance level. Age Group No Claim Claim 16 up to 25 170 74 25 up to 40 240 58 40 up to 55 400 44 55 or older 190 24 Total 1,000 200 With Excel inputs and formulas

3. Are younger drivers more likely to have accidents in their
driveways? Traffic engineers tabulated types of car accidents by
drivers of various ages. Out of a total of 82,486 accidents
involving drivers aged 15-24 years, 4243 of them occurred in a
driveway. Out of a total of 219,170 accidents involving drivers
aged 25-64 years, 10,701 of them occurred in a driveway. Use the
0.05 level of significance.

A large car insurance company is conducting a study of accidents
for male and female drivers. They want to know if on average male
drivers (who tend to be thought of as more aggressive drivers) have
more accidents than female drivers. Data on the number of accidents
in the past 5 years is collected for randomly selected drivers who
are insured by this company. An analysis of the results produced
the following summary statistics.Group Statistics NMeanStd DeviationStd Error MeanMale322.191.710.3026Female311.231.380.2482Using α=0.01, do...

An insurance company is interested in estimating the percentage
of auto accidents that involve teenage drivers. Suppose the
percentage of auto accidents that involved teenage drivers last
year was 15%. The company wants to know if the percentage has
changed this year. They check the records of 600 accidents selected
at random from this year and note that teenagers were at the wheel
in 60 of them.

auto accidents...

An insurance company believes that 30% of drivers are careless.
The probability that a careless driver will have an accident in any
one-year period is 0.4. The probability that a careful driver will
have an accident in any one-year period is 0.2. Find the
probability that a driver will have an accident next year given
that she has had an accident this year.

1. The Allstate Insurance Company determined the average number
of years between accidents for drivers in a large number of U.S.
cities. The ‘Accidents’ sheet in the ‘Lab12 Chp 10n11 S20’
spreadsheet contains the results for 32 randomly selected cities
east of the Mississippi River and 32 randomly selected cities west
of the Mississippi River.

A car insurance company suspects that the younger the driver is,
the more reckless a driver he/she is. They take a survey and group
their respondents based on age. Of 217 respondents between the ages
of 16-25 (Group 1), 183 claimed to wear a seat belt at all times.
Of 398 respondents who were 26+ years old (Group 2), 322 claimed to
wear a seat belt at all times. Find a 95% confidence interval for
the difference in proportions. Can...

The research department of an insurance company conducted a
survey of the cause of automobile accidents in the last calendar
year. A random sample of 200 policies written on single persons
revealed that 60 had been in at least one accident. A similar
survey of 300 policies written on married persons revealed that 75
had been in at least one accident. At the .05 level of
significance, is there a significant difference in the proportion
of the population of single...

In any given year, an insurance company believes the
following:
-0.6 of drivers are safe.
-0.25 of safe drivers wear seatbelts
-0.10 of unsafe drivers wear seatbelts
-0.10 of safe drivers experience an accident in a year
-0.20 of unsafe drivers experience an accident in a year
-Given a driver experiences an accident, the driver has
probability 0.01 they will be taken to the hospital if they were
wearing a seatbelt
