Median mean to find the center of the data
Answer:
Test statistic = - 2.29
Pvalue = 0.0110
Step-by-step explanation:
The hypothesis :
H0 : p = 0.3
H1 : p < 0.3
Test statistic :
z=pˆ−p/√p(1−p)/n
pˆ = 0.2
Z = (0.20 - 0.30) / √(0.30(1 - 0.30) / 110
Z = - 0.1 / √0.0019090
Z = - 0.1 / 0.0436931
Z = - 2.29
Test statistic = -2.29
The Pvalue :
P(Z < -2.29) = 0.0110
5 divide by 30 equals 6.12 minus 6 equals 6 so she has to make at least 6 pies.
3 nickels and 1 quarter add to $0.40.
The person has 11 times that amount, so has 11 quarters and 33 nickels.
Answer:
Question 5.
a) 118°
b) 131°
Step-by-step explanation:
<u>Part a:</u>
I'm sorry I find it tricky to explain this, you would get more confused than you are now.
<u>Part b:</u>
All four interior angles of a quadrilateral are equal to 360° so
75°+ 86°+ 68°+m°= 360°
229° +m° = 360°
m°= 360°-229°
m°= 131°
