(2) what number distinctive segment are there if the subsequent subgroup is comprised of 4 individuals ?.

(3) what number distinctive segment are there if the fouth subgroup is comprised of 6 individuals ?

(4) what number distinctive parcel are there if the second and fouth subgroups have 4 and 6 individuals separately ?

(5) The coordinator picks a segment of individuals at irregular .Find the likelihood that the quantity of individuals in the second and fouth subgroups of the picked segment are not 4 and 6 separately.

Bill battles that individuals spend somewhere in the range of 0 and 80 minutes every day tuning in to music, and he demands that no scope of times is any almost certain than some other.

15. In an examination analyzing overweight and hefty school

football players, Mathews and Wagner (2008) found

that on normal both hostile and protective linemen

surpassed the in danger measure for weight list

(BMI). BMI is a proportion of body weight to tallness

squared and is ordinarily used to order individuals as

overweight or corpulent. Any worth more noteworthy than 30 kg/m2

is viewed as in danger. In the investigation, an example of

n 17 hostile linemen arrived at the midpoint of M 34.4 with a standard deviation of s 4.0. An example of n 19

protective linemen arrived at the midpoint of M 31.9 with s 3.5.

a. Utilize a solitary example t test to decide if

the hostile linemen are altogether over the

in danger model for BMI. Utilize a one-followed test

with .01.

b. Utilize a solitary example t test to decide if the

guarded linemen are fundamentally over the in danger

standard for BMI. Utilize a one-followed test with .01.

c. Utilize an autonomous estimates t test to decide

regardless of whether there is a critical contrast between

the hostile linemen and the cautious linemen.

Utilize a two-followed test with .01
