Bighorn sheep are lovely wild creatures found all through the western United States. Leave x alone the age of a bighorn sheep (in years), and let y be the death rate (percent that pass on) for this age bunch. For instance, x = 1, y = 14 implies that 14% of the bighorn sheep somewhere in the range of 1 and 2 years of age kicked the bucket. An irregular example of Arizona bighorn sheep gave the accompanying data:

x 1 2 3 4 5

y 12.2 20.9 14.4 19.6 20.0

x = 15; y = 87.1 ; x2 = 55; y2 =1577.17; xy = 275.6

(a) Draw a disperse chart.

(b) Find the condition of the least-squares line. (Round your responses to two decimal spots.)

= + x

(c) Find r. Discover the coefficient of assurance r2. (Round your responses to three decimal spots.)

r =

r2 =

Clarify what these actions mean with regards to the issue.

The connection coefficient r estimates the strength of the direct connection between a bighorn sheep's age and the death rate. The coefficient of assurance r2 measures the clarified variety in death rate by the relating variety in age of a bighorn sheep.

The coefficient of assurance r estimates the strength of the straight connection between a bighorn sheep's age and the death rate. The relationship coefficient r2 measures the clarified variety in death rate by the comparing variety in age of a bighorn sheep.

Both the connection coefficient r and coefficient of assurance r2 measure the strength of the direct connection between a bighorn sheep's age and the death rate.

The connection coefficient r2 measures the strength of the direct connection between a bighorn sheep's age and the death rate. The coefficient of assurance r estimates the clarified variety in death rate by the comparing variety in age of a bighorn sheep.

(d) Test the case that the populace connection coefficient is positive at the 1% degree of importance. (Round your test measurement to three decimal spots.)

t =

Find or gauge the P-estimation of the test measurement.

P-esteem > 0.250

0.125 < P-esteem < 0.250

0.100 < P-esteem < 0.125

0.075 < P-esteem < 0.100

0.050 < P-esteem < 0.075

0.025 < P-esteem < 0.050

0.010 < P-esteem < 0.025

0.005 < P-esteem < 0.010

0.0005 < P-esteem < 0.005

P-esteem < 0.0005

(e) Given the outcome from part (c), is it reasonable to discover appraisals of y for a given x worth dependent on the least-squares line model? Clarify.

Given the absence of meaning of r, forecast from the least-squares model may be misdirecting.

Given the meaning of r, forecast from the least-squares model is viable.

Given the meaning of r, expectation from the least-squares model may be deceiving.

Given the absence of meaning of r, expectation from the least-squares model is useful.

. An occasion coordinator is planing a program for a gathering of 20 individuals who need to set out on a touring trip. Because of space imperatives at the offices to be visited the coordinator parcels the gathering into five non-void subgroups. The quantity of individuals in the subgroups may differ starting with one subgroup then onto the next.

(a) what number various segments are there for the coordinator?

(b) what number various parcels are there if the subsequent subgroup is comprised of 4 individuals

(c) what number various parcels are there if the fourth subgroup is comprised of 6 individuals

A public report found that treating individuals properly for hypertension diminished their general mortality by 20%.

Treating individuals sufficiently for hypertension has been troublesome in light of the fact that it is assessed that half of hypertensives don't realize they have hypertension, half of the individuals who do know are insufficiently treated by their doctors, and half who are properly treated neglect to follow this treatment by taking the correct number of pills.

On the off chance that the former half rates were each diminished to 40% by monstrous training program, at that point what impact would this change have on the general death rate among genuine hypertensives; that is, would the death rate decline and, assuming this is the case, which level of passings among hypertensives could be forestalled by the schooling program?
