Question If 0≤α<2π, find all values of α that satisfy the equation 4sin2α−18sinα−10=0.
(a) Can a normal distribution be used for the p) distribution? Explaini Yes, 0p and nq are both less than 5; Yes, np and nd are both greater than 5 . No, np is greater than 5 , but nq is less than 5. No, nq is grester than 5 , but np is less than 5 . No, np and ng are both less than 5. (b) State the hypotheses. H0​:ρ=0.5;H1​:ρ=0.5H0​:ρ=0.5;H1​:ρ<0.5H0​:ρ<0.5;H3​ A ρ=0.5H0​:θ=0.5;H1​:ρ>0.5​ (c) Compute p̂. Compute the corresponding standardized sample test statistic. (Round your answer to two decimal places.)
