The manager of an orchard expects about 70% of his apples to exceed the weight requirement for ""Grade A"" designation. At least how many apples must he sample to be 90% confident of estimating the true proportion within ± 4%?

356

Step-by-step explanation:

We are given that p=0.7, and a 90% confidence interval. Also, we know the margin of error to be 0.04, the sample size is calculated as:

#The sample size is calculated as:

Hence, at least 356 apples must be sampled to get a true proportion with the 4% ME.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
