Question

Using the Statistical tables, find the P-value of this test below:

The probability that a rose bud blooms is p. In a random sample of 500 rose buds, 240 of them bloomed.

With the data obtained in a random sample, a hypothesis test at the 1% level of significance is carried out to determined why p is different from 0.45.

Expert Solution

Step 1

Given,

In a random sample of 500, 240 found bloomed.

$p_{0} = 0.45$

$\hat{p} = \frac{x}{n} = \frac{240}{500} = 0.48$

Step 2

Hypothesis :

$H_{0} : p = p_{0} V s H_{1} : p \neq p_{0}$

Step by step
