Answer:
188 weeks of data must be sampled.
Step-by-step explanation:
From the information given, we can deduce that:
The Margin of error is within = 200
The confidence interval = 95%
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The standard deviation = 1400
The number of weeks the data must be sampled can be determined by using the formula for sample size which is:
n = 188.24
n ≅ 188
Thus, 188 weeks of data must be sampled.
Answer:
The number of apple for 1 cup of water is 1.5 apples
Step-by-step explanation:
Given as :
The number of cups of water = 91 cups
The number of apples for every 91 cups of water = 140
Let The number of apple for 1 cup of water = n
<u>Now, From unitary method :</u>
∵ For every 91 cups of water , the number of apple needed = 140
∴ For every 1 cup of water , the number of apple needed =
I.e n =
or, n = 1.5 apples
The number of apple for 1 cup of water = n = 1.5 apples
Hence The number of apple for 1 cup of water is 1.5 apples Answer
