Answer:
x = 5±2√7
Step-by-step explanation:
This quadratic cannot be factorised via the factorisation method, so we use the quadratic formula :
x = or x =
(The reason I did 2 equations is because brainliest does not allow me to do the ± in the equation insert thing )
x = or x =
x = or x=
x = or x =
x = or x =
Hope this helped and brainliest please

Step-by-step explanation:
The statistical inference may be defined as the process of using the data analysis to infer the properties of an underlying distribution for a probability.
In the context, for testing the population proportion p, the following conditions are used to verify the inference procedures so as to make the statistical inferences :
