What is the value of 67th percentile in a standard normal distribution?

Vikki [24]2 years ago
8 0

Let Z be a random variable following the standard normal distribution with mean µ = 0 and standard deviation σ = 1.

The 67th percentile of the distribution is the value z that separates the bottom 67% of the distribution from the top 100% - 67% = 33%. In terms of probability, we have

Pr[Z ≤ z] = 0.67

Use the inverse CDF for the normal distribution (or lookup z scores in a table) to find

z = ɸ⁻¹(0.67) ≈ 0.4399

where ɸ(z) is the CDF for the normal distribution.

Artemon [7]

After defeating the Spanish armada, the British settlers settled along the eastern coast claimed all territory from newfoundland to Florida for the king .

In particular, the planting of a colony at Cuppers Cove (Cupids, Conception Bay) by the London and Bristol Company in 1610 and the southern Avalon plantation in the early 17th century was responsible for the first British settlement in Newfoundland.

Between Trespassed in the south and Salvage in the north, there were at least one family in 30 distinct villages along Newfoundland's east coast by the 1670s.

Following the defeat of Spanish Armada, they settled in Newfoundland, which typically included a  period of apprenticeship servitude.
