Find the missing value.<br> (√24-√k)(√24+√k)=5
Anna [14]

Answer:

  • <u>k = 19</u>

Step-by-step explanation:

<u>Identity</u>

  • (a + b)(a - b) = a² - b²

<u>Simplifying the LHS (Left Hand Side)</u>

  • (√24-√k)(√24+√k)
  • (√24)² - (√k)²
  • 24 - k

<u>Equating to the RHS</u>

  • 24 - k = 5
  • k = 24 - 5
  • <u>k = 19</u>

astra-53 [7]

Answer:

The value of the standard error for the point estimate is of 0.0392.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In a randomly selected sample of 100 students at a University, 81 of them had access to a computer at home.

This means that n = 100, p = \frac{81}{100} = 0.81

Give the value of the standard error for the point estimate.

This is s. So

s = \sqrt{\frac{0.81*0.19}{100}} = 0.0392

The value of the standard error for the point estimate is of 0.0392.
