coldgirl [10]

Answer:

10%

Step-by-step explanation:

Given:

Total number of racers = 270

Number of racers completed the race = 243

Number of racers gave up = 20

Now,

The number of racers who did not complete the race

= Total number of racers - Number of racers completed the race

= 270 - 243

= 27

Therefore,

The percentage of racers who did not complete the race

= $\frac{\textup{number of racers who did not complete}}{\textup{Total number of racers}}\times100\%$

= $\frac{\textup{27}}{\textup{270}}\times100\%$

= 10%

Answer: Police can be 95% confident that true population proportion lies in (2%, 5%).

Step-by-step explanation:

Interpretation of confidence interval of population proportion : A person can be 95% confident that true population proportion lies in it.

Given : From time to time police set up roadblocks to check cars to see if the safety inspection is up to date. At one such roadblock they issued tickets for expired inspection stickers to 22 of 628 cars they stopped.

95% confidence interval for the true proportion of all drivers with expired inspections = (2%, 5%).

Interpretation : Police can be 95% confident that true population proportion lies in (2%, 5%).

There are two machines available for cutting corks intended for use in wine bottles. The first produces corks with diameters tha

Rainbow [258]

Answer: 0.7887

Step-by-step explanation:

Let x be the random variable that represents the diameters of the corks .

Given : The first produces corks with diameters that are normally distributed with mean 3 cm and standard deviation 0.08 cm.

i.e. $\mu=3\ cm\ \ ,\sigma=0.08\ cm$

Acceptable corks have diameters between 2.9 cm and 3.1 cm.

Then, the probability that the first machine produces an acceptable cork will be :_

$P(2.9$

∴ The probability that the first machine produces an acceptable cork= 0.7887
