Answer:
There is evidence to support the claim that there is a linear correlation between the heights and pulse rates of women
Step-by-step explanation:
given that the heights (in inches) and pulse rates (in beats per minute) for a sample of 11 women were measured.
correlation coefficient r = 0.7200

(two tailed test at 5% significance level)
r difference = 0.7200
Std error of r = 
Test statistic t = r difference/std error = 3.1128
df =9
p value=0.012458
since p <alpha, we reject H0
There is evidence to support the claim that there is a linear correlation between the heights and pulse rates of women
Answer:
Step-by-step explanation:
given that in a lottery game, a player picks 5 numbers from 1 to 46
If 4 of the 5 numbers match those drawn, the player wins second prize.
Assuming the numbers are chosen without repitition we find that the player can choose 5 numbers in 46C5 ways.
To win the prize he must choose 4 numbers form the 5 numbers in the prize and remaining 1 number any other number.
i.e. no of ways to get II price = choosing 4 numbers out of 5, and one number from 41
= 
Probability of winning this prize
=
13 and 7 are the correct numbers
Answer:
x = 7
Step-by-step explanation:
These angles are corresponding angles which mean that they're equal to each other:
7x - 4 = 5x + 10
7x - 5x = 10 + 4
2x = 14
x = 14/2
x = 7
