Answer:
Step-by-step explanation:
Given that
mu = 1502.5 pages
Sample mean x bar = 1511.4 pages
Std deviation =s= 35.7 pages
Sample size n = 40
By assuming random samples since only sample std dev is know we can say that sample mean x bar follows a t distribution with
mean =1511.4 and std error =
Test statistic t = Mean diff/STd error = 1.613
df = 39
Answer:
Options A and D.
Step-by-step explanation:
Coplanar points are points that lie in same plane. If 4 points are in same line they are collinear and then they will be coplanar. If the 4 given points lie in same plane then also they will be coplanar. If they do not lie in same plane they will not be coplanar. The points can lie on different lines. Four or more points might or might not be coplanar.
The correct options are A and D.
