An investigative bureau uses a laboratory method to match the lead in a bullet found at a crime scene with unexpended lead cartr

Basile [38]

Answer / Step-by-step explanation:

In this exercise, we know that the agency collected 1,829 bullets which according to the agency, all came from different source.

The number of pair of bullet is :

(1,829) = 1, 829 ! / 2! ( 1,829 - 2 ) = 1, 829 x 1,828 x 1827 ! / 2 x 1 x 1,827

( 2 )

= 6, 108,413,724 / 3654

= 1671,706.

Also, we know that the agency found 658 matches. According to this, the chance of false positive ( that is, the agencies find a match but the bullets are from two different source ) is

P (False positive ) = 658 / 671,706

= 0.000979.

The probability is small to an extent, therefore, we should have confidence in the agency forensic report and evidence

We are continuing to study the difference in average time for completion for the two matching schemes. However, this time we had

IgorLugansk [536]

Answer:

We are 95% confident that the time to completion for the same color method is between 4.617 less to 9.383 less than the different color method.

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence for the difference in the completion time of treatment is and d is,

CI = (-4.617, -9.383)

The parameter of the study is defined as:

treatment_s - treatment_d

Consider the 95% confidence interval, (-4.617, -9.383). The confidence interval consists of all negative values.

This implies that the difference between the completion time of treatment s and d is less than 0, i.e. the completion time of treatment s is less than that for treatment d.

Thus, the complete statement is:

"We are 95% confident that the time to completion for the same color method is between 4.617 less to 9.383 less than the different color method."

The scatter plot below shows the relationship between the length (x) in meters and mass f(x) in kg of a marine animal

Vlad [161]

F(x) = -9 + 10.3x probably.
It's definitely not the first or last option as they have negative gradients (i.e. negative x-coefficient) and so represent a negative correlation. The data given tells us there is a positive gradient and so a positive correlation.
It could be the second option as the second and third are not so vastly different but I would go for the third because it appears to most closely fit the data pattern.
