David wants to complete a hypothesis test with the least amount of probability for error. If he sets the significance level to 1
Brrunno [24]

Answer:

He could increase the sample size

Step-by-step explanation:

In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.

The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made

Opposite reciprocal of -2/3? geometry/algebra
Ulleksa [173]
The answer would be -3/2

A reciprocal is the inverse of a number.
When using this in fractions just switch the numerator and denominator. This is done by dividing the fraction by one, but in the case of a negative fraction you would divide by negative 1.
