svetoff [14.1K]

Answer:

At least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence

Step-by-step explanation:

Minimum sample size required can be found using the formula

N≥(\frac{z*s}{ME} )^2 where

  • N is the sample size
  • z is the corresponding z-score of 95% confidence level (1.96)
  • s is the standard deviation (10)
  • ME is the margin of error (0.5)

then N≥(\frac{1.96*10}{0.5} )^2 =1536.64

Then, at least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence
