That would be 4(16) - 8 - (4(0) - 8) = 64 - 9 - 0 + 8 = 63 Answer
Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
A) the z score for 95% is 1.96
Multiply by the deviation:
1.96 x 0.005 = 0.0098
Now add and then subtract that from the mean:
4.035 - 0.0098 = 4.0252
4.035 + 0.0098 = 4.0448
The interval is (4.0252, 4.0448)
B) 4.035 +/- 1.96 x sqrt( 0.005/sqrt(25))
= 4.035 +/-0.00196
Answer: ( 4.033, 4.037)
C) the conclusion is that both 4.020 and 4.055 are out of the range.
4.020 is below the lowest range and 5.055 is higher than highest range.
So from the onset, the answer to this question would be
OPTION B.In a conjunction, / is true when both / and / are<span>
TRUE</span>; otherwise, / is
FALSE.
A conjunction refers to a compound statement, developed by combining two statement often through the use of the word '
AND'. For example, the two statements, 'Roses are Red' (statement
p) .... 'Violets are Blue' (statement
q), can be combined to form a conjunction that reads 'Roses are Red and Violets are Blue.' When it comes to conjunctions, it is or equivalent to the intersection of the two sets of statements (p and q → p ∩ q) which therefore means that <span>
in order for the conjunction to be true, both statements must be true, otherwise, the conjunction is false.
</span>
Attached below is a truth table that seeks to further explain the point (note: ^ represent the conjunction).
