Answer:
the probability that a test correctly classifies as positive individuals who have preclinical disease
Step-by-step explanation:
Sensitivity represents the true positive percentage
Lets take an example if there is 90% sensitivity that means there are 90% people who have the target disease considered the test positive
So according to the given options, it is the probability in which if the test is done in a correct manner so this means that the positive individuals have the preclinical disease
Therefore the first option is correct
Since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.
Here:
we can use 1 sample proportion test to check the claim of John
H₀ : p₀ = 0.4
H₁ : p₀ ≠ 0.4
Test statistic is
z = p - p₀/√p₀(1-p₀)n
Let X be the random variable denoting the number of heads.
Now p = X/n
= 8/50
= 0.16
p₀ = 0.4
1-p₀ = 1-0.4
= 0.6
z = -3.464
since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.

6^2 + 17 + 12
First, let's start with
. Basically, the '2' above the 6 indicates that the number appears twice in multiplying.
can be described as 6 × 6 as well. 36 should be your answer for 6 squared.
Second, our problem should look like: 36 + 17 + 12. One can simply do this on a calculator or count on their fingers. Once you add all of the numbers up, you should get 65.

Answer:
Anita Bath's home was worth $ 593,195.62 in 2007.
Step-by-step explanation:
Given that from 1992 to 2007 the average home price increased by 8% per year, and in 1992 Anita Bath bought a house for $ 187,000, to determine what was it worth in 2007 the following calculation must be performed:
2007 - 1992 = 15
187000 x 1.08 ^ 15 = X
187000 x 3.172 = X
593,195.62 = X
Therefore, Anita Bath's home was worth $ 593,195.62 in 2007.
