Answer:
0.3051
Explanation:
mean (μ) = 20.8, standard deviation (σ) = 5.6 and the number of samples (n) = 36 scores.
Z score also known as standard score is used in probability to measure the number of standard deviations by which the value of what is being measured is above or below the mean. It is given by the equation:
Z score (z) =
For x = 21.6,
From the probability table:
P(x < 21.6) = P(z < 0.86) = 0.3051 = 30.51%
The probability that the mean score for the sample is less than 21.6 = 30.51%
Yes, because Pluto is known as a dwarf-planet since 2006. It was considered a normal size planet in 1930. Since then it was demoted to a dwarf.
A planet is a planet no matter the size.
Answer: 0.03
Explanation:
The standard error will be calculated as:
= ✓p(1-p) / ✓n
where,
p = 57/186 = 0.3065
n = 186
We then slot the values back into the formula and this will be:
= ✓p(1-p) / ✓n
= ✓0.3065(1 - 0.3065) / ✓186
= ✓(0.3065 × 0.6935) / ✓186
= ✓0.2124884 / ✓186
= 0.03
