There are 255 students this term completing this same assignment. Assuming they calculated the CI correctly, how many students s

andrey2020 [161]

Answer:

The number of students we expect to have an interval that does not contain the true mean value is, $255\times [\alpha\%]$ .

Step-by-step explanation:

A [100(1 - α)%] confidence interval for true parameter implies that if 100 confidence intervals are created then [100(1 - α)] of these 100 confidence intervals will consist the true population parameter value.

Here α is the significance level. It is defined as the probability rejecting the claim that the true parameter value is not included in the 100(1 - α)% confidence interval.

It is provided that 255 students create the same confidence interval, correctly.

Then the number of students we expect to have an interval that does not contain the true mean value is, $255\times [\alpha\%]$

For instance, if the students are creating a 95% confidence interval for mean then the number of students we expect to have an interval that does not contain the true mean will be:

The significance level is:

$Confidence\ level=100(1-\alpha)\\\frac{95}{100}=(1-\alpha)\\\alpha =1-0.95=0.05$

Number of students we expect to have an interval that does not contain the true mean will be: $255\times [\alpha\%]=255\times 0.05=12.75\approx13$

Thus, 13 of the 255 confidence intervals will not consist the true mean value.

Last month, Jasmine's family drove to a resort in the mountains. They drove 240 mi. On the first day of the trip. On the second

Monica [59]

Answer:

1000 miles

Step-by-step explanation:

Given the following :

Number of miles driven :

First trip = 240 miles

Second day = 205 miles

Third day = 315 miles

Fourth day; miles driven before arriving at their final destination = 220 miles

Total number of miles driven after 4 days before reaching their destination :

(240 + 205 + 315 + 220) = 980 miles

However, they still haven't reached their destination ;

Using front end estimation :

We can take the total miles recorded and make an estimation based on the first digit of the recorded miles traveled:

In other to estimate 980 using front end estimation : the actual number is replaced with a number with only one nonzero digit (which is the first digit)

Hence,

980 - - - - > we round the digit after 9 either 1 or 0, since it is greater than 4, then it is rounded to and added to the first digit, all subsequent dots are rounded to zero

Hence 980 - - - - > 1000

Hence, estimated miles driven = 1000 miles
