Naily [24]

Answer:

there is sufficient evidence to support the claim that male student have a sitting height different of 91.4 cm.

Step-by-step explanation:

p value = 0.0198

level of significance = 0.05

hypothesis:-

$H_{0}:\mu=91.4$

$H_{1}:\mu\neq91.4$

decision:-

p value = 0.0198 <0.05

so, we reject the null hypothesis.]

Answer:

The $96^{th}$ percentile is 1.751

Step-by-step explanation:

The following information is missing in the question:

Mean,

$\mu = 0^\circ C$

Standard Deviation,

$\sigma = 1^\circ C$

We are given that the distribution of distribution of errors is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.96

$P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.96$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x}{1} = 1.751\\\\x = 1.751$

$P_{96} = 1.751$

1.751 degree Celsius is the thermometer reading corresponding to $96^{th}$ percentile.
