Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that

against the alternatives
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis
, then P value is
(1)
a)significance level
from 1 eq we get
Therefore
FROM Z TABLE
B) significance level
from 1st equation we get
Therefore
FROM Z TABLE
C) significance level
from 1 eq we get
Therefore

She must win the next 8 consecutive games to get 80% and after that loose the next 12 games to get to 50%.
<h3>How to find the probability of winning?</h3>
She has won 8 out of 12 days. Thus, percentage of winning is;
P(winning) = 8/12 * 100%
P(Winning) = 75%
To arrive at 80% winning, it means that the number of extra consecutive games she must win is;
(8 + x)/(12 + x) = 80/100
10(8 + x) = 8(12 + x)
80 + 10x = 96 + 8x
2x = 16
x = 8
Thus, she must win the next 8 consecutive games to get 80%.
For her to get to 50% after that, it means that;
(16 - x)/(20 - x) = 50/100
(16 - x)/(20 - x) = 1/2
2(16 - x) = 20 - x
32 - 2x = 20 - x
x = 12

Explanation: just counted the numbers under the leaf part hope i helped
<h3><u>AnswEr</u><u> </u><u>:</u></h3>
The 2 unknown numbers are 4 and 5 .
<h3><u>Expla</u><u>nation</u><u> </u><u>:</u></h3>
Let the numbers be x and x + 1.
From the given information,






But, as we know -5 is not a natural number,
Hence, x = 4 .
<u>So the 2 unknown numbers are</u><u> </u><u>:</u>
- x + 1 = 4 + 1 = 5 [2nd number]
