Answer:

(c) The t-distribution is bell shaped

(e) The t-distribution has more values at the extremes than a standard normal distribution

(f) The t-distribution is centered at 0

Step-by-step explanation:

When the sample size is small or population variance is unknown, and we have to estimate population parameter then t- probability distribution is used.

 The t-distribution has properties as follows:

  1. The mean of t-distribution is 0. Thus, option (f) is correct.
  2. t-distribution is normal. Thus, option (c) is correct.
  3. As compare to standard normal distribution, t-distribution has more values at the extremes. Thus, option (e) is correct.

if you save three pennies on January 1, six pennies on January 2, nine pennies on January 3, and continue this pattern for one y
Katarina [22]

Answer:

2003.85

Step-by-step explanation:

I realize I'm a year late, but the math of the previous answer was so terrible I'm honestly too horrified to let this be.

You have save by an increasing amount of 3 pennies per day. You start with 3 and build from that, each day, for 365 days. First, you must figure out what amount of pennies you shoved into your account on the final 365th day.

An= a1+(n-1)d

An=term you want

a1= term you begin with

n= term you want

d= constant amount

A_365= 3 + (365-1)*3

A_365= 1095

Arithmetic Sum: Sn = N/2 (a1 + an)

365/2 * (3 + 1095) = 200385.

This means you've invested a total of 200385 PENNIES after 365 days.

The question asks for dollars, not your rusting lincoln's.

As (I hope) you know, 1 Dollar = 100 pennies

200385 pennies/100 = 2003.85.

This means you have $2003.85 in your account by the conclusion of the 365th day.
