Question

A trend was observed in the growth of population in Saya Islands. The population tripled every month. Initially the population of Saya Islands was 100. what would be population after 4 months ? a) 100*4^3 b) 100*3^4 c) 100*3*4 d) (100^3)^4

Answer 1

To calculate the confidence interval, you must find p′, q′, andEBP. p′ = 0.842 is the sample proportion; this is the point estimate of the population proportion. Since CL = 0.95, then α = 1 – CL = 1 – 0.95 = 0.05 (α) = 0.025. Use the TI-83, 83+, or 84+ calculator command invNorm(0.975,0,1) to find z 0.025.
