Can someone please help? Thank you.

10) A fitness app states that its users achieve an average step count of 8,000 steps per day. To verify this, you
randomly select 20 users and record their daily step counts: [7500, 8200, 7900, 8100, 8300, 8100, 8200, 7900,
8000, 8300, 7600, 8200, 8000, 7900, 8000, 7800, 8300, 7900, 8100, 8000]. Is there evidence to support the
app's claim at a 1% significance level?
