I need a help fellows, the attached image is a sample of my data to be analyse. I tried worked on weighted mean score which the score is outside right of the table, please help me check if i am on point. And what other statistical analysis could sweet this kind of data?
try Anova or chisquare analysis

Please why are you asking.

Just curious. If you are interested in Pure Mathematics, I strongly recommend that you start to look for a scholarship overseas or try AIMS (African Institute of Mathematical Sciences). I am not sure Uniben is strong in Pure Mathematics (well except for Alufohai, but I guess he is retired now).

PLS SOMEONE SHOULD HELP ME WITH THIS . 1,A vehicle makes a journey that forms a triangular shape such that the distance CD=40km, AD=50km, angle ACD=115degrees and angle D=25degrees. FIND THE THIRD SIDE OF THE TRIANGULAR SHAPE.


2.GIven that COS B =squareroot2 times B + Xsquared diveded by 4X, FIND THE POSSIBLE VALUES OF X if B=45.

IF (SIN B)squared = 1 + COS B, zerodegrees less than or equal to B less than or equal to 90degrees.


Sorry for the typing irregularities i used a small phone to type this.

5 men can complete a job in 4 days. In how many days can 10 men working at 1/4 of the previous rate complete the job?

5 men do the job in 4 days at the normal rate

So, 1 man will take longer than 5 men, thus:

1 man does the job in 5*4 = 20 days at the normal rate

10 men will take shorter than 1 man, so:

10 men do the job in 20/10 = 2 days at the normal rate

10 men working the job at 1/4 the normal rate will take longer, hence:

10 men do the job in 2*4 = 8 days at 1/4 the normal rate.
