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 limitations at the offices to be visited the orga-nizer parts the gathering into five non-void subgroups. The quantity of individuals in the subgroups may change starting with one subgroup then onto the next.

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

(b) what number various parts are there if the second and fourth subgroups have 4 and 6 individuals separately?

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

(b) what number various parts are there if the second and fourth subgroups have 4 and 6 individuals separately?

(c) The coordinator picks a segment of individuals at arbitrary. Discover the likelihood that the quantity of individuals in the second and fourth subgroups of the picked parcel are not 4 and 6 separately.

Here are the noticed frequencies from four classes: 5, 6, 8, 13.

Expect we need to utilize a 0.05 importance level to test the case that the four classes are on the whole similarly likely. (Integrity of fit test)

What is the invalid theory?

What are the normal recurrence for every one of the four classifications?

What is the estimation of the test measurement?

What is the basic worth?

What do you finish up about the given case?

The retirement ages of a gathering of steel laborers are recorded underneath. Develop a histogram with 4 classes utilizing Microsoft Excel, Google Sheets, or GeoGebra. You will transfer the diagram in the following inquiry.

{64,60,57,63,61,64,50,62,60,56,53,62,54,60,64,53,61,58,60,64,57,56,64,61,63}

What is the populace mean of the information?

What is the populace change? (Round to four decimal spots. Note: s^2 implies s2

What is the populace standard deviation? (Round to four decimal spots)

The information is

As indicated by Chebyshev's hypothesis, in any event 88.9% of the information falls between around 47.62 and ___________. (Round to the closest 100th
