Does anyone know the definition of a riemann hypothesis : \ i need

In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 12. ... The Riemann zeta function ζ(s) is a function whose argument s may be any complex number other than 1, and whose values are also complex.

The coach should start recruiting players with weight 269.55 pounds or more.                                                    

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 225 pounds

Standard Deviation, σ = 43 pounds

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

We have to find the value of x such that the probability is 0.15

Calculation the value from standard normal z table, we have,  

Thus, the coach should start recruiting players with weight 269.55 pounds or more.
