Let X1​,X2​,…,Xn​ be a random sample from a distribution with probability density function f(x∣θ)=θxθ−1 if 0<1≤x and θ>0} and 0 otherwise. The decision rule of the uniformly most powerful test of \ ( H−​{0}: theta =1 V against H1​:θ>1 at the 0.05 level of significance is Select one: A. reject H0​ if ∏i=1n​xi​≤c where c satisfies 0.05=P(∏i=1n​Xi​≤c∣θ=1). B. ​ reject H0​ if ∏i=1n​xi​≥c where c satisfies 0.05=P(∏i=1n​Xi​≥c∣θ=1). C. reject H0​ if ∑i=1n​xi​≤c where c satisfies 0.05=P(∑i=1n​Xi​≤c∣θ=1). D. reject H0​ if ∑i=1n​xi​≥c where c satisfies 0.05=P(∑i=1n​Xi​≥c∣θ=1).
