Students were measuring distances and found one to be 2.04 m. When they asked the teacher if their measurement was correct, the

IgorLugansk [536]

Answer:

The percentage error is 5.56%

Explanation:

Given

$Measured (M) = 2.04m$

$Actual (A)= 2.16m$

Required

Determine the percentage error

Percentage error (P) is calculated as follows:

$P = \frac{|A - M|}{A} * 100\%$

$P = \frac{|2.16 - 2.04|}{2.16} * 100\%$

$P = \frac{|0.12|}{2.16} * 100\%$

$P = \frac{0.12}{2.16} * 100\%$

$P = \frac{12\%}{2.16}$

$P = 5.56\%$

Hence:

<em>The percentage error is 5.56%</em>

The circumference of a circle is 43.96 kilometers. What is the circle's diameter?

Oxana [17]

13.99 kilometers is the diameter.

Divide the circumference (43.96) by 2(pi), which should give you a radius of 6.99. You should then proceed to multiplying that by 2, since radius is half of the diameter, giving you 13.99.

hoa [83]

Based on the calculations, the value of the test statistic and p-value are equal to -2.1213 and 0.0169 respectively.

<u>Given the following data:</u>

Standard deviation = 2.

Sample mean = 19.4.

Number of sample = 50.

Hypothesized mean = 20.

<h3>How to compute the test static?</h3>

Mathematically, the value of the test statistic can be computed by using this formula:

$Z=\frac{\bar{x}\;-\;\mu}{ \frac{\sigma}{\sqrt{n} } }\\\\Z=\frac{19.4\;-\;20}{\frac{2}{\sqrt{50}}}\\\\Z=\frac{-0.6}{0.282842 }$

zₓ = -2.1213.

From the z-table, the p-value is given by:

P(Z < zₓ) = P(Z < -2.1213)

P(Z < -2.1213) = 0.0169.

Since the p-value is equal to 0.0169 less than α = 0.05, we would reject H₀ : µ equal to 20. Thus, we would conclude that µ < 20.
