October-December 37
Answer:
Yes, There is significant evidence to conclude that hockey players' birthdates are not uniformly distributed throughout the year.
Step-by-step explanation:
Observed value, O
Mean value, E
The test statistic :
χ² = (O - E)² / E
E = Σx / n = (67+56+30+37)/4 = 47.5
χ² = ((67-47.5)^2 /47.5) + ((56-47.5)^2 /47.5) + ((30-47.5)^2/47.5) + ((37-47.5)^2/47.5) = 18.295
Degree of freedom = (Number of categories - 1) = 4 - 1 = 3
Using the Pvalue from Chisquare calculator :
χ² (18.295 ; df = 3) = 0.00038
Since the obtained Pvalue is so small ;
P < α ; We reject H0 and conclude that there is significant evidence to suggest that hockey players' birthdates are not uniformly distributed throughout the year.

The number of Apples that were in the given fruit salad is approximately; 2170 Apples.
<h3>How to work with ratio questions?</h3>
We are given the ratio of apples to oranges as;
A:O = 31:11
Now, we are told that there are 2940 apples and oranges in total.
Thus, the fractions of apples and oranges of the total will be;
Apple fraction = 31/(31 + 11) = 31/42
Orange Fraction = 11/42
Thus;
Number of Apples = (31/42) * 2940
Number of Apples = 2170 Apples

Math is used in construction everywhere.Math is used in construction to measure parts, how many feet, inches, etc. to do and how high to go up.A great example is in the scaling of blueprints, where an architect creates a scale model of the building so that it can fit on paper.
