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

Find the value of the length x rounded to 1 DP.

ivanzaharov [21]

Answer:

x = 13.6 cm

Step-by-step explanation:

part A:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(39) = \frac{6}{adjacent}$

$adjacent = \frac{6}{tan(39)}$

$adjacent = 7.41$

part B:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(44) = \frac{6}{adjacent}$

$adjacent = 6.213$

Total length of x:

part A + part B

$7.41 + 6.213$

$13.6$ cm
