find the value of k . show complete solution

P(-1.088<T<k)=0.8 for df = 11

P(k<T<2.087) =0.945 df= 23

t(0.98. df = 14) =k

T Score: 1.049 DF: 14 Significance Level: .05 One-tailed The P-Value is .155975. The result is not significant at p < .05. Here's my Question. Can someone explain in detail how this calculator comes up with this P- value. Can it be solved by hand? None of the calculators online show any work. Thank you

Find the solution to the following equation for an age-structured population: ∂/∂t P(t,a)+ ∂/∂a P(t,a)=−δ(a)P(t,a), a≥0,t≥0 P(0,a) = P0(a) P(t,0) = C where C > 0 is a constant. Bonus: What is the asymptotic behavior of the population (total size, age-distribution if possible) as t → ∞? If limit exists, is it a solution to the PDE and, if so, what kind of solution?
