Answer:
56,000 bees or 8,000 bees every day for 7 days
Step-by-step explanation:
16 ounces = a pound so 16,000 bees we need to know how many bees we need so we do 16,000 times 3 =48,000 bees but we go .5 left so we divide the 16,000 into 8,000 and add that to 48,000 to = 56,000 bees to produce 3.5 pounds of honey every week there are also 7 days in a week so you can do 56,000 divide by 7 to = 8,000 bees per day to get 3.5 pounds of honey
Answer:
May 4th has become known as Star Wars Day, an unofficial holiday that gets its origin from a line of dialogue in the first movie released in George Lucas' space saga, "Star Wars: A New Hope." ... After that, the saying crops up regularly in the films, books, video games and across the Star Wars universe.
Answer:
a) The mean is 0.15 and the standard error is 0.056.
b) 1. Yes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions p, in samples of size n, the mean is and the standard error is . The Central Limit Theorem applies is np > 5 and np(1-p)>5.
In this question:
So
(a) Find the mean and the standard error of the distribution of sample proportions.
So the mean is 0.15 and the standard error is 0.056.
(b) Is the sample size large enough for the Central Limit Theorem to apply?
np = 40*0.15 = 6 > 5
np(1-p) = 40*0.15*0.85 = 5.1>5
So yes
