This line of code where you are calculating the average should be outside of any condition, otherwise if for some reason the array passed to the function doesn't have any boolean that line of code will never be read, so you can actually do this math operation in the return:

function avg(mixedArr) {
  if (mixedArr.length === 0) {
    return null;
  } 
  let arrSum = 0;
    for (let i = 0; i < mixedArr.length; i++) {
      if (typeof mixedArr[i] === 'number') {
        arrSum += mixedArr[i];
      } else if (typeof mixedArr[i] === 'string') {
        arrSum += mixedArr[i].length;
      } else if (typeof mixedArr[i] === 'boolean') {
        if (mixedArr[i] === true) {
          arrSum += 1;
        }
      }else{
        throw new Error("Invalid data type")
      }
    }
    return arrSum/mixedArr.length 
  }

Also, you're missing the last test which is to throw an error. For that you just need an else with the syntax for throwing an error inside. The jasmine test will continue to be red but your answer will be correct don't worry.
