Answer:
1.01 < µ < 1.03
Step-by-step explanation:
We want to construct a 95% confidence interval. Our sample size is 25, so we use a t-value. The degrees of freedom are 24 (always one less than the sample size).
The t-value we get is: 2.064
We have:
x = 1.02
σ = 0.03
See the attached photo for the construction of the confidence interval...
Answer:
The extremes are 5 and 64.
The middle terms are 80 and 4.
Step-by-step explanation:
Given the proportion:
5 : 80 :: 4 :64
To find:
The extreme and middle terms of the given proportion.
Solution:
The given statement is in proportion if and only if the product of extremes i.e. the numbers at both the ends is equal to the product of middle numbers.
OR
First number
Fourth number = Second number
Third number
First of all, let us check the two products.
5
64 = 320
And the second product:
80
4 = 320
The product is same therefore, the given numbers are in proportion.
The extreme terms are the first and the fourth numbers.
i.e. The extremes are 5 and 64.
The middle terms are 80 and 4.
