Afinancial advisor believes that the proportion of investors who are risk-averse (that is, try to avoid risk in their investment decisions) is at least 0.6. a survey of 33 investors found that 21 of them were risk-averse. formulate a one-sample hypothesis test for a proportion to test this belief.

It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.

Step-by-step explanation:

We have to perform an hypothesis test of a proportion.

The null and alternative hypothesis are:

We state a significance level of 0.1.

The sample proportion is

The standard deviation is

The test statistic z is calculated as

The P-value of z=0.247 is P=0.8. This value is bigger than the significance level, so the efect is not significant.

It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.
