Answer: No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.
Step-by-step explanation:
Since we have given that

Mean height = 61.5 inches
Standard deviation = 4.4 inches
n = 100
So, test statistic value would be

At 10% level of significance, in two tail test ,
z = 1.28
Since 1.28 > -2.727
So, we will accept the null hypothesis.
Hence, No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.
Answer:
y= -0.5 x +3
Step-by-step explanation:
at x=0 , y=3
at x=2 , y=2
y= ax+b
b=3
2=2a+3
2a= -1
a= - 0.5
then
y= -0.5 x +3
Step-by-step explanation:
6x-7+3x-29=180 (corresponding angle)
9x-36=180
9x=180+36
9x=216
x=24.
6x-7=8y+17
144-7-17=8y.
8y=120
y=15.
therefore, x=24°, y=15°.
hope this helps you.
