Answer:
The statement that cushion A is twice as popular as cushion B cannot be verified
Step-by-step explanation:
From the question we are told that:
Sample size n=38
Type a size A
Type a size B
Generally the probability of choosing cushion A P(a) is mathematically given by
Generally the equation for A to be twice as popular as B is mathematically given by
Therefore Hypothesis
Generally the equation normal approx of p value is mathematically given by
Therefore from distribution table
Therefore there is no sufficient evidence to disagree with the Null hypothesis
Therefore the statement that cushion A is twice as popular as cushion B cannot be verified
If A and B are equal:
Matrix A must be a diagonal matrix: FALSE.
We only know that A and B are equal, so they can both be non-diagonal matrices. Here's a counterexample:
Both matrices must be square: FALSE.
We only know that A and B are equal, so they can both be non-square matrices. The previous counterexample still works
Both matrices must be the same size: TRUE
If A and B are equal, they are literally the same matrix. So, in particular, they also share the size.
For any value of i, j; aij = bij: TRUE
Assuming that there was a small typo in the question, this is also true: two matrices are equal if the correspondent entries are the same.
