Answer: C- Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

I used a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:
<em>tInterval 9.68,1.23,125,0.99</em>
It resulted in 9.68 ± 0.287805.
Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.
A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.

Answer:
Check the explanation
Step-by-step explanation:
A. All polynomials of the form p(t) = a + bt2, where a and b are in: This means that A is closed under scalar mult and vector addition, and includes the zero vector.
B.All polynomials of degree exactly 4, with real coefficients: what this means is that under vector addition, B isn't closed, and it does not consist of the zero vector. What it consist of is just polynomials with degree exactly 4. Let f=x4+1f=x4+1 and let g=−x4g=−x4. Both are in B, but their sum is not, because it has degree 0.
C. All polynomials of degree at most 4, with positive coefficients: what this means is that C is not a subspace for the reason that the positive coefficients make zero vector impossible. The restriction there also makes C not closed under multiplication by the scalar −1.
So the answer is only A :D
