In a study of parents' perceptions of their children's size, researchers asked parents to estimate their youngest child's height

maks197457 [2]

Answer:

B) TS = -6.51, p-value = 0.0000

Step-by-step explanation:

Sample size, n = 39

μ = 7.5 cm

Null hypothesis, H₀ = 7.5 cm

(I.e. Average height of youngest child is 7.5 cm)

Alternative hypothesis, $H_{a}\neq 7.5$ (The youngest child's age is underestimated by 7.5 cm)

Standard deviation, $\sigma = 7.2 cm$

In order to be able to reject the null hypothesis,

the formula for the test statistic:

$t = \frac{- \mu}{s/\sqrt{n} }$

$t = \frac{- 7.5}{7.2/\sqrt{39} }$

t = -6.51

P - value

P(x < 7.5) = P(z < -6.51)

Checking the p-value for z < -6.51 in the normal distribution table

P(z < -6.51) = 0.0000

p - value = 0.0000

I need the answer in under 34 min

Answer:

I. 1 cup is $4.50

2 cups is $9.00

3 cups is $13.50

ll. 6 cups is $27.00

Step-by-step explanation:

Now since the number of cups is proportional to the total cost of frozen yoghurt,and the cost of 4 yoghurts cups where given .ie. $18.00

then 1 cup is $18/4 which is $4.50 per one cup, thus the other cost of cups are given.

therefore 6 cups is 6•18/4 which is $27.00.

hence 5 cups is 5•18/4 which is $22.50.
