Gnagey's Gnot Bad Investment Inc. develops a new crypto-backed security, that leverages multiple cryptocurrencies to generate a monthly income investmentplan that promises a variable return each month.

Utah's Pension Plan is considering purchasing this investment plan for their public employees, but only if it is assured the plan averages at least $180 monthly income. The Pension Plan collects data for a hypothesis test at the 0.05 significance level and finds out for a random sample of 50 months, the scheme had investment returns with an average value of $190. The population standard is assumed to be known at $75.

What is the test statistic for the hypothesis test?
