What are atoms of the same element with varying number of neutrons

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
