Question

P(-d 13 years ago

Answer 1

Divide 0.5408 by 2. Then use the resulting value of probability to find the value of z from the standardised normal distribution table. z = d.

Answer 2

divide 0.5408 by 2 check the number on both positive and negative z table

0.5408/2 =0.2704

Answer 3

by the way tables they are not all same but they have different techniques to find the same answer

Answer 4

thank you!!!

Answer 5

u r welcom

Answer 6

I have another question! could you guys help? @REMAINDER @kropot72

Answer 7

yes

Answer 8

a county has been experiencing a mean of 35.3 motor vehicle deaths each year.
whats the probability of more than two motor vehicle deaths on any given day

Answer 9

btw I am not getting the right answer with dividing by two with the previous question

Answer 10

wat do u get

Answer 11

okay so is p(-d<z<d) = .5408 and divide by two thats .2704
and i looked on the chart and it gives me -.61 but the answer is .74 so how do they get that

Answer 12

did 'nt they gave u a standad deviation ?for the second question

Answer 13

nope

Answer 14

this is what it says.

Answer 15

the standard distribution = \[\sqrt{mean}\]

Answer 16

the formula is given. P(x) = \[\frac{ mean ^{x} \times e^{-mean} }{ x! }\]

Answer 17

and if it asks for more than 2, then that would be P(a) = 1-complement of p(a)
so 1- [p(0) +p(1)+p(2)] but the answer isnt right.

Answer 18

oh this is poisson

Answer 19

yes lol myyyyy bad

Answer 20

this was a question from last chapter.

Answer 21

i also don't get their answer ok @zarkon even if he is offline but he will find lets hope he will solve it because most of my stats question have been answered by him.

Answer 22

ok thanks

Answer 23

lets try that one of d again

Answer 24

okay so theres two different problems.
a. if P(-d<z<d) = .5408, find d
b. if P(-e<z<e) = .2586, find e

Answer 25

yes the first one is o.74

check this
\

and on the table 0.7704 is 0.74
