kotykmax [81]

Answer:

a) The blue whale has about 200 times more mass

Step-by-step explanation:

(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)

Answer:

z=-2.09

Step-by-step explanation:

Given that a study of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only 41% of the time.

Set up hypotheses as:

$H_0: p=0.50\\H_a: p$

(left tailed test at 5% significance level)

Standard error = 0.043

Sample proportion p = 0.41

p difference = $0.41-0.50=-0.09$

Test statistic Z = p diff/std error

= $\frac{-0.09}{0.043} \\=-2.09$

Z = -2.09
