Inventory Management and Control Systems in Covid-19 Pandemic Era: An Exploratory Study of Selected Health Institutions in Anambra State, Nigeria Table 4.6: Effectiveness of IMS in COVID-19 pandemic era Value Df Asymp. Sig. (2-sided) Pearson Chi-Square 15.336 a 16 .060 Likelihood Ratio 9.443 16 .071 Linear-by-Linear Association 1.911 1 .167 N of Valid Cases 63 Source: Field survey 2022 Table 4.6 above shows the test of hypothesis of the degree of effectiveness of re-order level, period- review and EOQ in the COVID-19 pandemic era. The result above shows that the Pearson’s Chi-Squared Statistical Test result is insignificant ( X 2 = 15.336, p- value =0.060). To further support the statistical position of the above result, the Likelihood Ratio of the test is 9.44 with a p- value of 0.071. Since the p-value of the test (0.060) is greater than 0.05, the null hypothesis was accepted. As a result, the researchers concluded that the inventory management systems being used in selected health institutions in Anambra state are not effective in the COVID-19 pandemic period at 5% level of significance. ii. Hypothesis II H O2 : the inventory management systems pose no significant challenge to health institutions in the COVID- 19 pandemic era. Below is the output of the test: Table 4.7: Challenges of IMS in COVID-19 pandemic era Value df Asymp. Sig.

The minimum expected count is .44. Source: Field Survey 2022 The result above shows that the Pearson’s Chi- Squared Statistical Test result is significant ( X 2 = 0.6377, p-value =0.001). To further support the statistical position of the above result, the Likelihood Ratio of the test is 0.6132 with a p- value of 0.003. Since the p-value of the test (0.001) is less than 0.05, the null hypothesis was rejected. Consequently, the researchers concluded that IMS pose significant challenges to health institutions in the COVID-19 pandemic era at 5% level of significance. The findings of the study are in tandem with the outcome of the studies earlier carried out by Onuorah (2019); Okerulu (2019);Agu, Obi-Anike & Eke (2016) iii. Hypothesis III H O3 : Inventory management systems (proxies by re- order level system, periodic review system and economic order quantity model) do not significantly influence optimal stock levels in selected health institutions in the COVID-19 era.
