Not sure why this is wrong.
If B is the standard basis of the space Pz of polynomials, then let B={1, t, t2, t3). Use coordinate vectors to test the linear independence of the set of polynomials below. Explain your work. (2 – t), (-3 – t)2, 1 + 18t - 5t? +43 Write the coordinate vector for the polynomial (2 – t)º, denoted p.. py = |(8,- 12,6, - 1)
Help with any of these?

You will perform a significance test of H0: μ = 19 based on an SRS of n = 25. Assume that σ = 13. Step 1: If x = 23, what is the test statistic z to 2 decimal places? Step 2: What is the P-value if Ha: μ > 19? Give your answer to 4 decimal places. Step 3: What is the P-value if Ha: μ ≠ 19? Give your answer to 4 decimal places.
