<p>
Suppose that a hypothetical healthcare inflation index, HCI, is computed by weighting three items as follows: "insurance premiums" is weighted at \(\omega_1 = 50\%\), and "medical products" and "medical services" are each weighted at \(\omega_2 = \omega_3 = 25\%\). Suppose that insurance premiums are growing at is 4% per year, and the annual inflation rate of medical products and medical services is 1% and 2%, respectively.</p>
<p>
What is the annual inflation rate of HCI? (<i>Note</i>: Your answer should be a number in percentage form. Do not enter '%').<br/><div class="inline" tabindex="-1" aria-label="Question 1" role="group"><div id="inputtype_68eb2cf5c1514cb1afcc3c7c258ced87_2_1" class=" capa_inputtype inline textline">
