Westminster Financial has released a summary of investment package information from the past fiscal year. During this time, Westminster provided a choice among twelve pre-designed investment packages. Westminster classified the packages into three categories according to riskiness. We're interested in the possible relationship between the age of an investor and the riskiness of the investment package she chose. So, there are two variables under consideration: age of Westminster investor ("under 35", "35-49", or "50+") and riskiness of investment choice ("risky", "moderate/mixed", or "conservative").The contingency table below gives a summary of the information released by Westminster regarding age and riskiness of investment package for a random sample of 150 investors. Each cell of the table contains three numbers: the first number is the observed cell frequency (fO); the second number is the expected cell frequency (fE) under the assumption that there is no relationship between the two variables age of Westminster investor and riskiness of investment choice for this past year; and the third number is the following value.Could not fit part 2 in the picture but the questions are asking for: type of test statisticvalue of test statistic critical value with level of significance of 0.05and can we reject the hypothesis that there is no relationship between the variables ago of westminster investor and riskiness of investment choice for this past year yes or no
