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

SAT
1 answer:
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.

larisa86 [58]

Answer:

Un cualidad en mi caracter es la templanza. Me cuido mucho de lo que vaya a comer. La segunda cualidad positiva mental es que lo que me propongo logro. En el terreno de las relaciones tengo dos. Por ejemplo con mis padres soy bueno hijo y con mi amiga siempre dispuesto de ayudar. En mi grupo de escuela me conocen como una persona amable. Finalmente, en la iglesia yo soy el que ayuda a los ancianos.

Explanation:

One quality of my character is temperance. I take good care of what I am going to eat. The second positive mental quality is whatever I set to accomplish, I will accomplish. In the personal relationships arena, I have two. For example, I am a good son with my parents and my friend I help her in whatever she may need. Within my school, people know me as amicable. Finally, in my church, I help the elderly.

What are the things you must do in the order to get full credit for the day?​
pashok25 [27]
You need to make at least the minimum payment each month, even during an interest-free period. Set up a Direct Debit for the full monthly balance, or for as much as you can afford to repay. This will mean you don’t miss a payment, which could lead to unwanted charges and the loss of any introductory rate. Missing payments could also damage your credit rating.
You’ll have a credit assessment by the card provider when you apply, which will usually include checking your credit reference file. A good credit rating will improve your chances of a successful credit application. It could also give you access to cards offering the lowest interest rates and/or promotional offers.
You need to be at least 18 to apply for a credit card. With some cards the minimum age is 21.
