The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was 0.9 −
kaheart [24]

Answer:

The proportion would be 0.1

Step-by-step explanation:

Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,

f(t) = 0.9 - 0.4\ln(t)

If t = 7 minutes,

f(7) = 0.9 - 0.4\ln(7)=0.9 - 0.77836=0.12164\approx 0.1

Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )

A score that is three standard deviations above the mean would have a z score of
tia_tia [17]

The value of z-score for a score that is three standard deviations above the mean is 3.

In this question,

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

Let x be the score

let μ be the mean and

let σ be the standard deviations

Now, x =  μ + 3σ

The formula of z-score is

z_{score} = \frac{x-\mu}{\sigma}

⇒ z_{score} = \frac{\mu + 3\sigma -\mu}{\sigma}

⇒ z_{score} = \frac{ 3\sigma }{\sigma}

⇒ z_{score} = 3

Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.
